A young mild-mannered American couple, Cliff (Zahn) and Cydney (Jovovich), are celebrating their marriage by hiking to a remote beach in Hawaii while on their honeymoon. On their way, they see two hitchhikers, Cleo (Shelton) and Kale (Chris Hemsworth). They offer the pair a ride but change their minds when the two seem possibly dangerous.After they begin the hike, the couple comes in contact with Nick (Olyphant), a solo hiker who claims to be an Iraq War veteran. Nick saves Cydney's life when she slips while attempting to cross a narrow ledge. The trio approaches a group of frightened female hikers discussing a double murder in Honolulu. The victims had their teeth pulled out and fingertips removed. Cliff suspects the hitchhiking couple are the murderers, and Cydney and Cliff discuss whether or not they should turn back, but decide to continue hiking with Nick. They subsequently meet up with Nick's sexy girlfriend, Gina (Sanchez) at the Secret Falls Waterfall.Cliff suspects Kale and Cleo are following them. When he notices their permits are missing, Cliff sees Kale and Cleo's bags by the trail and goes through them, but he does not find the permits. After making camp, Nick and Cliff split up to search for Kale and Cleo. Cliff runs into a guide who is bringing Cliff the permits they left behind. Cliff and Nick return to the campsite. Nick brings a goat he has killed, and Gina proceeds to butcher the animal, explaining she had learned how while working in the meat department of a grocery store.The following day, Kale and Cleo are arrested for the murders. A container full of pulled teeth is found in one of their bags. The two couples are relieved by the arrests, and they continue their hike to the beach. Cliff rents two kayaks so he and Nick can explore a marine cave.As Gina idly looks through the photos on Cydney and Cliff's video camera, she is terrified when she realizes the couple are not who they claim to be. Gina sets off after Nick and Cliff, while Cydney chases after Gina.Flashbacks reveal that Cliff and Cydney are drug-addicted sociopaths who murdered the newlyweds. They kill people and steal their identities in order to, as Cliff explains, "live a hundred different lives and achieve a kind of immortality". It is also revealed that "Cliff" had planted the bag of teeth in Kale and Cleo's bag to frame them for the murders.In the Sea cave, Cliff suddenly reveals his true murderer identity and shoots Nick in the head. Gina witnesses this from the cliffs above. Then Cliff shoots at her, but misses. Cydney sneaks up on Gina and attacks her. Gina is stabbed in the leg but manages to push Cydney off the cliff into the water.Even though they haven't had a signal during the entire trip, Gina fortuitously receives a call on her cell phone from a phone company representative. She begs him to call the police. She spots Cydney below in the kayak just as Cliff pops up over the cliff ledge to grab her feet. Gina stabs him in the hand with Cydney's knife and flees.While Cliff chases Gina and Cydney kayaks ashore to intercept the police, Nick, saved by the titanium plate in his head from his war wound, wakes up. Gina runs into a group of men searching for their stolen kayaks, who tell her she is safe now. Cliff tries to convince the men that Gina is irrational due to meth use. But one of the group happens to be an EMT and notices Cliff's enlarged pupils, which undermines his story. So Cliff shoots and kills the entire group of men. Gina uses Cliff's distraction as an opportunity to run toward the beach. Nick arrives and fights Cliff, getting the upper hand. At that point, the police arrive by helicopter with a rifle aimed at Nick. Cydney is also in the helicopter, and the police want her to confirm that Nick is the killer, but she pauses. Cydney identifies Cliff as the murderer and says he ruined her life. The police sharpshooter kills Cliff as he reaches for his gun to kill Nick. Later Nick finally proposes to Gina in the helicopter but due to their traumatic encounters, they both agree to not having a honeymoon., Question: Who shoots Nick in the head ?
Answer: Cliff shoots Nick in the head.

(June 2015) (Learn how and when to remove this template message)Anna Quarrels (Rhonda Griffin), librarian in the Rare Books Room, is approached by Mr. Jamison from the University of Chicago who wishes to study Mary Shelley's original manuscript for "Frankenstein; or, The Modern Prometheus". After he's finished, Anna is about to return the manuscript to the stacks when she discovers that Jamison has switched blank paper for the manuscript and walked out of the library with it. Investigating, she learns he used a fake I.D. to access the Rare Books Room and so hires Private Detective, David Raleigh (Justin Lauer) to track him down. David finds fingerprints on the sign-in sheet and discovers the man claiming to be Jamison is really Dr. Winston Berber, an unscrupulous scholar with doctorates in Physics, Mathematics, Folklore, and Philosophy. Berber (Bill Moynihan) is meanwhile gloating over his collection of rare manuscripts; along with the Shelley manuscript, he has obtained the originals of Guy Endore's "The Werewolf of Paris" (1933) and James Putnam's "Mummy" (1993). He now seeks the first edition of Bram Stoker's "Dracula" (1897) to complete his collection. Berber has invented an "Archetype Inducer" and plans to use the manuscripts to bring the four greatest monsters from horror history to life to do his bidding.David has been so busy at the video store he runs that he has not yet located Berber, but when Berber returns to the library looking for the first edition of "Dracula", Anna recognizes him, holds him at bay with a pair of scissors, and phones David and tells him to hurry over. Before David can arrive, Berber zaps Anna with a taser, steals the "Dracula" manuscript, and takes both the book and Anna to his laboratory. She regains consciousness and finds herself handcuffed to a table. Berber informs her that she is just what he needs: a virgin between the ages of 20 and 35 to be sacrificed naked in order to make the Archetype Inducer work. David breaks into the lab, having found Berber's address with an internet search. He overcomes Berber and releases Anna. She grabs the manuscripts, and the two hurriedly leave the lab. Unfortunately, Berber had already turned on the Archetype Inducer, and while David and Anna are making their escape, the four monsters step out of the machine. But strangely, The Mummy (Joe Smith), Frankenstein's monster (Thomas Wellington), the Wolfman (Jon Simanton), and Dracula (Phil Fondacaro) are all midgets. Dracula is unhappy that he has been brought to life three feet tall, but Berber assures him that he and the other monsters can be increased in stature if he can recapture Anna. The monsters offer to get her for him.Anna isn't too happy either about the $6200 invoice presented by David for his services, and Anna's supervisor, Miss Christina (Kristin Norton), is herself unhappy because Anna keeps dodging her romantic advances. When her advances are again dodged, Christina stays late at the library in order to make love to the first edition of "Jane Eyre" in the Rare Book Reading Room. She hears a noise out on the floor, and in investigating falls prey to Dracula's net. Back at the lab, Berber is unhappy because Christina was not Anna, and insists he needs Anna. Dracula forces him to try the procedure anyway, and when it does not work, the antagonists set out again to find Anna.At David's house, Dracula is unable to get Anna's address from David, and tries to bite his neck. David exposes his crucifix and races out the door. Assuming that he will lead them to Anna, the monsters and Berber follow as David leads them to the library. When the monsters attempt to capture Anna, David grabs Berber and threatens to break his neck if they don't leave Anna alone. David pulls out Berber's taser to threaten Dracula, who simply zaps it and causes it to explode. Anna and David are taken back to the lab and Berber prepares for the procedure. Dracula asks for assurance that it will work this time, but Berber won't guarantee it because Anna is not a virgin. Dracula suggests that they find another virgin in order to go through the procedure, but Berber says that will unbalance things. The only way to keep everything balanced is to find a male virgin opposite of Anna. After asking, Dracula is assured that David is indeed a virgin, and the preparations continue while David tries to come up with an idea. But at the last minute, it is Anna who has an idea. She points out to the monsters that, if they stay in the real world they will eventually die like all humans do. But if they return to the pages of the novels from whence they came, they will live on forever as the legends they are. Berber pushes the red button to start his machine, and David and Anna escape from their cuffs. Rather than the two being sucked into the machine, Christina reappears as a Viking, grabs Berber, and they both disappear. Anna and David conclude that the machine turned the two into archetypes of a Viking and a mad scientist. Having had a little time to ponder Anna's idea, Dracula tells David to press the red button again, as the monsters have chosen to return to their own lands as the legends they are rather than to die in the real world. Before the four are sucked back into the pages of their respective novels, Dracula tells Anna that she is wise "for someone who has not yet lived a single lifetime. But do not fear," he adds, "we will always be with you... in your nightmares."Anna later shows up at David's video store, gives him a check for $6200 and informs him that Berber's lab has been torn down. She also gives him a book, the first English language edition of "Venus in Furs". David thanks her and admits that he saw the movie in "1970, directed by Jess Franco (Jesus Franco), starring Klaus Kinski. Actually, there was an earlier version directed by Larry Buchanan, the guy who did Zontar: The Thing from Venus (1966). Actually, I think there's a '94 version but it's all in Dutch...," he drones on. Anna interrupts him with a kiss., Question: What did David threaten Dracula with?
Answer: Berber's taser.
