(August 2015) (Learn how and when to remove this template message)Recently divorced Helen Grace (Mary-Louise Parker) moves into the Spiderwick Estate in the woods with her children when it is given to her by her elderly aunt Lucinda (Joan Plowright), though identical twins Jared and Simon (Freddie Highmore) and their older sister Mallory (Sarah Bolger) do not want to move from New York. When Jared uncovers a dumbwaiter system behind a wall, he finds a monogrammed key and discovers the study of the late owner of the estate, Arthur Spiderwick (David Strathairn). Jared then uses the key to open a chest. In it, he finds Spiderwick's field guide to fairies; although an attached note warns him not to read it, he does so anyway. When Jared explained about his discovery on the existence of magical creatures, Helen and Mallory don't believe him.Soon after, Jared meets a brownie named Thimbletack (Martin Short), who explains that magical creatures are normally invisible, but can reveal themselves at will. He tells Jared about a protective circle that Arthur Spiderwick placed around the house and gives him a stone with a hole through which he can see fairies.However, a shapeshifting ogre named Mulgarath (Nick Nolte) wants the field guide for himself so he can rule over all fairy-kind. He sends his goblins, led by Redcap the Pompous Goblin General, to obtain it and they kidnap Simon, mistaking him for Jared. Meanwhile, Jared meets Hogsqueal (Seth Rogen), a hobgoblin and bitter enemy of Mulgarath because Mulgarath killed his entire family. Hogsqueal gives Jared the ability to see fairies without the aid of the stone by spitting in his eyes. Mulgarath lets Simon go and berates Redcap for failing his master. Jared finds Simon and both fight over the book, which is spotted by the goblins. Together, the twins flee to the house, though Simon is injured when one bites his leg. Mallory is then attacked by the goblins, but manages to kill several using her fencing skills, making her finally realize that Jared is right. Inside, Thimbletack informs them that Mulgarath will kill all humans and fairies who oppose him if he gets the book.They resolve to destroy the book by cremating it in a fire, but the flames do not harm it due to a protective spell placed upon it. With no other options, the children decide to visit their great-aunt Lucinda, now in a psychiatric hospital, for advice. While Simon distracts the goblins, Mallory and Jared manage to reach a tunnel under the estate. They are pursued by a mole troll and only narrowly escape it when it is struck by an oncoming vehicle. Lucinda tells them that they need to find Arthur Spiderwick and have him destroy the book. However, Arthur is being held captive by Sylphs, a type of fairie. Suddenly, Mulgarath's goblins attack them and steal several pages from the book before they are driven off. In the woods, Mulgarath violently berates Redcap for not bringing all of the book, as most of the information in the stolen pages were useless, but he is pleased by when he discovers that one of them has information that tells them how to break the protective circle by moonrise. Mulgarath and Redcap prepare to make the potion for the upcoming night. Meanwhile Helen, who drives Jared and Mallory home, doesn't believe them on what's going on and accuses them of using that as an excuse for wanting to go back to New York. Jared then gets in a heated argument with her on why his father left her because of her not listening and starts yelling. Once home, Jared tells Helen he hates her and doesn't want to live with her. Later, Hogsqueal warns Jared, Simon, and Mallory about Mulgarath's plan and gives Simon and Mallory the ability to see fairies. Jared then tries to call his father, but Mallory tells him he has moved in with another woman and will not return to them as he promised, making Jared regret his angry words he told Helen.Jared, Simon, and Mallory use the book to summon Arthur Spiderwick's pet, a griffin, which takes them to the realm of the Sylphs. There they meet Arthur, who has not aged but is also unaware of the time he has spent there. The children ask him to destroy the book only to find that Thimbletack had switched the pages. He also informs them that the Sylphs won't allow them to leave as they'll be held captive like he is, but helps them escape by distracting them. Once home, they try to convince Helen of the imminent threat of the goblins and the existence of magical creatures. At first, Helen refuses to listen until Thimbletack appears and they show her the goblins outside, finally shattering her disbelief and making her agree to help stop the attack. At this time, the goblins have finished spreading the potion, which successfully breaks the circle when the moon rises. Jared, Simon, Mallory, and Helen arm themselves with steel knives and home-made tomato sauce/salt bombs prepared by Simon earlier. The family successfully fend off the attacking goblins, though the house suffers considerable damage in the process. When they are forced into the kitchen by Mulgarath's arrival, they place all of their bombs into the oven, detonating them and killing all of the goblins, including Redcap.Richard (Andrew McCarthy) enters the house and tells Jared that he came to apologize. Jared, realizing that it is not his father, stabs him in the stomach, revealing him to be Mulgarath in disguise. Jared escapes with the book through the dumbwaiter while Mulgarath gives pursuit in snake form and injures Thimbletack. On the roof, Jared throws the book into the air; Mulgarath transforms into a raven and catches it, but he is snatched and eaten by Hogsqueal, avenging his family and the scattered pages fall on the ground. Jared then climbs down the roof and he and Helen reconcile for their argument earlier and for the latter to apologize for not believing him. Hogsqueal and the Graces pick up the scattered pages of the Field Guide.The Graces bring Lucinda back to the house, showing her the repairs being made to the house in the aftermath of the goblin attack and reintroducing her to Thimbletack, who is alive. Suddenly, the Sylphs appear, bringing Arthur, as he was allowed to visit his home since the book was now safe. He cannot remain outside of the fairie realm, or he will turn to dust. Lucinda asks to be taken with him instead; the Sylphs transform her back into her six-year-old self and spirit the two away as the Graces watch and then resume their normal lives with Thimbletack, Hogsqueal, and the Griffin.

Answer: Who is being held captive by Sylphs?


Question: The story is told from the viewpoint of Lt. Werner (Herbert GrÃ¶nemeyer), who has been assigned as a war correspondent on the German submarineÂ U-96 in October 1941. He meets its captain (JÃ¼rgen Prochnow), chief engineer (Klaus Wennemann), and the crew in a raucous French bordello. Thomsen (Otto Sander), another captain, gives a crude drunken speech to celebrate his Ritterkreuz award, in which he openly mocks not only Winston Churchill but implicitly Adolf Hitler as well.The next morning, they sail out of the harbour of La Rochelle to a cheering crowd and playing band. Werner is given a tour of the boat. As time passes, he observes ideological differences between the new crew members and the hardened veterans, particularly the captain, who is embittered and cynical about the war. The new men, including Werner, are often mocked by the rest of the crew, who share a tight bond. After days of boredom, the crew is excited by another U-boat's spotting of an enemy convoy, but they soon locate a British destroyer, and are bombarded with depth charges. They narrowly escape with only light damage.The next three weeks are spent enduring a relentless storm. Morale drops after a series of misfortunes, but the crew is cheered temporarily by a chance encounter with Thomsen's boat. Shortly after the storm ends, the boat encounters a British convoy and quickly launches four torpedoes, sinking two ships. They are spotted by a destroyer and have to dive below the submarine's rated limit. During the ensuing depth-charge attack, the chief mechanic, Johann, panics and has to be restrained. The boat sustains heavy damage, but is eventually able to safely surface in darkness. An enemy tanker remains afloat and on fire, so they torpedo the ship, only to realize that there are still sailors aboard; they watch in horror as the sailors, some on fire, leap overboard and swim towards them. Following orders not to take prisoners, the captain gives the command to back the ship away.The worn-out U-boat crew looks forward to returning home to La Rochelle in time for Christmas, but the ship is ordered to La Spezia, Italy, which means passing through the Strait of Gibraltarâan area heavily defended by the Royal Navy. The U-boat makes a secret night rendezvous at the harbour of Vigo, in neutral although Axis-friendly Spain, with the SS Weser, an interned German merchant ship that clandestinely provides U-boats with fuel, torpedoes, and other supplies. The filthy officers seem out of place at the opulent dinner prepared for them, but are warmly greeted by enthusiastic officers eager to hear their exploits. The captain learns from an envoy of the German consulate that his request for Werner and the chief engineer to be sent back to Germany has been denied.The crew finishes resupplying and departs for Italy. As they carefully approach Gibraltar and are just about to dive, they are suddenly attacked by a British fighter plane, wounding the navigator. The captain orders the boat directly south towards the African coast at full speed. British ships begin closing in and they are forced to dive; it is later implied that the ships used radar to locate the sub. When attempting to level off, the boat does not respond and continues to sink until, just before being crushed by the pressure, it lands on a sea shelf, at the depth of 280 metres. The crew work desperately to make numerous repairs before running out of oxygen. After over 16 hours, they are able to surface by blowing out their ballast of water, and limp back towards La Rochelle under cover of darkness.The crew is pale and weary upon reaching La Rochelle on Christmas Eve. Shortly after the wounded navigator is taken ashore to a waiting ambulance, Allied planes bomb and strafe the facilities, wounding or killing many of the crew. Ullmann, Johann and the 2nd Watch Officer are killed. Frenssen, Bootsmann Lamprecht and Hinrich are seriously wounded. After the raid, Werner leaves the U-boat bunker in which he had taken shelter and finds the captain, badly injured by shrapnel and bleeding from the mouth, watching the U-boat sink at the dock. Just after the boat disappears under the water, the captain collapses and dies. Werner runs to his body, recoils, and quickly glances around at the destruction, his face frozen with distress. He then looks down at the captain's body, with tears in his eyes.

Answer: Who is given a tour of the boat?


Question: Two teenagers come upon an apparently abandoned military installation. They take advantage of what appears to be a swimming pool to skinny dip. The teenagers are attacked by an unseen force and disappear under the water. A light activates in the main building and a silhouetted figure investigates the screams, but is too late to help.A determined but somewhat absent-minded insurance investigator named Maggie McKeown is dispatched to find the missing teenagers near Lost River Lake. She hires surly backwoods drunkard Paul Grogan to serve as her guide. They come upon the abandoned compound, which functioned as a fish hatchery before being militarized. They discover bizarre specimens in jars and indications of an occupant. Maggie locates the drainage switch for the outside pool and decides to empty it to search the bottom, but the moment she activates it a haggard and frantic man begins to panic and attacks her, attempting to stop the draining until he is subdued by Grogan. The two found a skeleton in the filtration trap of the empty pool, and learn it was filled with salt water. The man awakens and steals their jeep, but crashes it due to his disorientation, and is taken to Grogan's home where they spend the night. They take Grogan's raft down the river, where the man wakes up and tells them that the pool in the facility was filled with a school of piranhas, and that Maggie released them. They are skeptical until they hear a dog barking and they come across the corpse of Grogan's friend Jack, who has bled to death from an attack on a fishing dock.The man reveals himself to be Doctor Robert Hoak, lead scientist of a defunct Vietnam War project, Operation: Razorteeth, tasked with engineering a ravenous and prodigious strain of piranha that could endure the cold water of the North Vietnamese rivers and inhibit Viet Cong movement. The project was shut down when the war ended, but some of the mutant specimens survived, and Hoak tended to them to salvage his work. Grogan realizes that if the local dam is opened, the school will have access to the Lost River water park, and the nearby summer camp where his daughter is in attendance. They encounter a capsized canoe with a boy whose father has been killed by the fish. Hoak rescues the boy but suffers mortal injuries when the school attacks him; he dies before he can reveal how to kill them. Blood from Hoak's corpse causes the piranha to tear away the raft's lashings, and they barely reach shore. Grogan stops the dam attendant from opening the spillway and calls the military.A military team led by Colonel Waxman and former Razorteeth scientist Dr. Mengers feed poison into the upstream section, ignoring the protests that the fish survived the first attempt. When Grogan discovers that a tributary bypasses the dam, Waxman and Mengers quarantine them to prevent the agitated pair from alerting the media. After they escape, Waxman alerts law enforcement to capture them. The school attacks the summer camp during a swimming marathon, injuring and killing many children and a supervisor. Grogan's daughter escapes due to her fear of water, and aids her camp mates in escaping.The school continues downriver. Waxman and Mengers arrive at the water park to intercept Grogan and Maggie, but the piranha attack the resort and kill many vacationers and Waxman. Grogan and Maggie commandeer a speedboat and rush to the shuttered smelting plant at the narrowest point of the river. Remembering the empty facility pond, Grogan realizes the fish can survive in salt water; if the school passes the delta, they will reach the ocean and spread over the world. He intends to open the smelting refuse tanks, hoping the industrial waste will kill the fish. They arrive at the plant ahead of the fish, but the elevated water level has submerged the control office, and Grogan must go underwater; he ties a rope around his waist and instructs Maggie to count to 100 before pulling him out. Grogan struggles to move the rusted valve wheel when the school arrives and attacks him. The assault hyperadrenalizes him, and he manages to open the valves just as Maggie pulls him to safety. Maggie takes Grogan back to the water park, where a massive MEDEVAC is tending to the victims; his injuries are severe and he is seen in a catatonic state.Mengers gives an on-site television interview, providing a sanitized version of events and downplaying the existence of piranha. Her voice is heard carrying out over a radio on the shore of a West Coast beach. As she says "there's nothing left to fear", the piranha's characteristic trilling sound drowns out the waves on a beach.

Answer:
Who stops the dam from opening?
