Movie plot title: Saw IV Movie plot: This article's plot summary may be too long or excessively detailed. Please help improve it by removing unnecessary details and making it more concise. (October 2015) (Learn how and when to remove this template message) A wax-coated microcassette is found in John Kramer's stomach during his autopsy. It reveals to Mark Hoffman, the detective called in to hear it, that the games, including his own, will continue. Elsewhere, two men - one with his eyes sewn shut, the other with his mouth sewn shut - awaken in a mausoleum, chained at the neck to a winch. The blinded man panics and activates the winch while attacking the muted man, who kills him and removes a key from his collar to free himself. Four days after Allison Kerry's death, a SWAT team led by Hoffman and Lieutenant Rigg finds her body, and Hoffman warns Rigg for breaking through an unsecured door to reach her. The scene is also investigated by Peter Strahm and Lindsey Perez, Kerry's FBI contacts, who received a message and a key from her. Noting Kramer's and Amanda Young's physical limitations, Strahm states they are looking for an unidentified accomplice; he soon becomes suspicious of Rigg, who has developed an obsession with saving people in the six months since the disappearance of Eric Matthews. That night, Rigg is attacked in his home; he awakens to learn that Matthews is alive and has ninety minutes to save himself, with Hoffman's life also at risk. Meanwhile, he must play his own game to face and overcome his obsession. The detectives are shown to be at each end of a large seesaw: Matthews is held atop an ice block by a chain-noose, and Hoffman is strapped to a chair with electrodes at his feet. If Matthews slips or too much ice melts, both men will die. A man later arrives to oversee the game. Rigg finds a pimp, Brenda, bound to a chair in his living room. He is implored to leave her, but he accidentally starts the trap by removing her gag, which slowly tears her scalp. He frees her, but kills her in self-defense when she attacks with a knife,...

Movie plot title: Friday the 13th Movie plot: In summer of 1958, Barry and Claudette, two Camp Crystal Lake counselors, sneak into a storage barn to copulate. Before they can engage, an unseen assailant enters and murders them. 21 years later in June 1979, Annie Phillips enters a small diner and asks directions to the reopened Camp Crystal Lake. Enos, a truck driver agrees to drive Annie halfway. An elder named Ralph reacts to this by warning Annie that the camp has a "death curse". During the drive, Enos explains that a young boy drowned at Crystal Lake in 1957, and the incident the following year. After Enos drops her off, Annie hitches a ride, but the second driver then chases her into the woods and slashes her throat. At the camp, counselors Ned, Jack, Bill, Marcie, Brenda and Alice and owner, Steve Christy refurbish the cabins and facilities. As a storm ensues, Steve leaves campgrounds to stock supplies. Soon, the killer arrives and begins to kill the counselors, including Steve. Worried, Alice and Bill, the only two left, leave the main cabin to investigate only to discover a bloody axe in Brenda's bed, the phones disconnected, and the cars inoperable. When the power goes out, Bill goes to check on the generator and is killed. Alice then heads outside and calls out for him and finds his dead body pinned to the back of the door. She screams and flees back to the main cabin to hide. Alice sees a vehicle pull up; thinking its Steve, she rushes out but instead sees a middle-aged woman named Pamela Voorhees, an "old friend" of Christy's. As Alice tries her news, Pamela reveals herself to be the mother of the drowned boy - Jason, blaming his death on the counselors having sex. She reveals herself as the killer when she violently rushes toward Alice with her knife. A chase ensues with Mrs. Vorhees attempting to kill Alice, but she escapes to the shore. Just as she eases, Pamela attempts to kill her again. During the final struggle, Alice decapitates her with a machete. Afterwards, a shaken Alice boards and falls asleep inside a canoe and floats to Crystal...

Movie plot title: The Abyss Movie plot: In 1988, the U.S. Ohio-class submarine USS Montana has an encounter with an unidentified submerged object and sinks near the Cayman Trough. With Soviet ships moving in to try to salvage the sub and a hurricane moving over the area, the U.S. government opts to send a SEAL team to Deep Core, a privately-owned experimental underwater drilling platform near the Cayman Trough to use as a base of operations. The platform's designer, Dr. Lindsey Brigman, insists on coming along with the SEAL team, despite her estranged husband Virgil "Bud" Brigman being the current foreman. During initial investigation of the Montana, a power outage in the team's submersibles leads to Lindsey seeing a strange light circling the sub. At the same time, one of Deep Core's crew, "Jammer", damages his breathing apparatus in an apparent panic, and falls into a coma. This prompts the admiral in charge of the operation to send Lt. Coffey, the SEAL team leader, to take one of the mini-subs and recover a Trident missile warhead from the Montana, just as the storm hits above. Coffey does not get permission from the Deep Core crew. The Benthic Explorer, which Deep Core is tethered to, is rocked by the storm, and the cable crane is torn from the ship. The crane falls into the trench and, without the mini-sub to disconnect the cable, Deep Core is dragged towards the trench, stopping just short of it. The rig is partially flooded, killing several crew members and damaging its power systems. Coffey shows little remorse when he and his SEALs return to the damaged base. Lindsey is sent in dive gear to retrieve some oxygen bottles from a damaged portion of the rig to give the crew enough time to wait out the storm. While working, she's accosted by a small, maneuverable pink/purple device, followed by a much larger one. Before she can take a picture as proof, the large craft zooms downward into the trench, leaving her to take fuzzy, smeared pictures of the smaller one following it. She coins the term "non-terrestrial intelligence", or "NTI". As the...
