Movie plot title: Tucker & Dale vs Evil Movie plot: College students Allison, Chad, Chloe, Chuck, Jason, Naomi, Todd, Mitch and Mike are going camping in West Virginia. While at a gas station, they encounter Tucker and Dale, two well-meaning hillbillies who have just bought the vacation home of their dreams: a run-down lakefront cabin, deep in the woods. On Tucker's advice, Dale tries to talk to Allison, but because of his inferiority complex and appearance, he only scares her and her friends. Tucker and Dale arrive at their decrepit cabin and begin repairing it. Nearby in the woods, Chad tells a story about the "Memorial Day Massacre", a hillbilly attack which took place 20 years ago. The college kids go skinny-dipping where Tucker and Dale are fishing, and Allison, startled, hits her head. Tucker and Dale save her, but her friends think she was kidnapped. When Allison wakes up in Tucker and Dale's cabin the next day, she is initially scared but befriends the two hillbillies. The other college kids arrive at the cabin to save Allison from her "psychopathic captors", and Chuck runs away to get the police. While Dale and Allison are inside the cabin, Tucker angers some bees and frantically waves around his chainsaw, which the college kids misinterpret as hostility. They scatter through the woods, and Mitch accidentally impales himself on a broken tree. After finding Mitch's body, Chad persuades the others that they are in a battle for survival. Allison's friends follow Tucker and Dale back to their cabin and see Allison helping out with construction of an outhouse, but they assume she is digging her own grave. The college kids attack, but Todd and Mike end up accidentally killing themselves, and Allison is accidentally knocked unconscious again by Dale's shovel. The other kids assume the hillbillies killed them when they see Tucker trying to save Mike from the wood chipper. Tucker and Dale think the college kids are suicidal and that contacting the police will make them murder suspects. Chuck arrives back with a sheriff, who expresses doubt over Tucker and...

Movie plot title: Watership Down Movie plot: According to Adams' Lapine language, culture and mythology, the world was created by the god Frith, who represents the Sun. All animals lived harmoniously, but the rabbits eventually multiplied, and their appetite led to a food shortage. At the prayers of the desperate animals, Frith warned the rabbit prince El-ahrairah to control his people, but was scoffed at. In retaliation, Frith gave special gifts to every animal, but some animals he made predators to prey upon the rabbits. Satisfied that El-ahrairah (Now also known as "Prince with a Thousand Enemies") had learned his lesson, Frith also gave the rabbits speed and cunning; while many would seek to kill them, the rabbits could survive by their wits and quickness. In the present, in the English countryside of Sandleford, Fiver, a rabbit seer has an apocalyptic vision and goes with his older brother Hazel to beg the chief to have the warren evacuated, but they are dismissed and attempt to make an exodus themselves. The group meets resistance from the warren's police force called the Owsla, but eight manage to fight and escape: Fiver, Hazel, Bigwig, Blackberry, Pipkin, Dandelion, Silver and Violet. As Fiver had foreseen, the warren is wiped out by human developers. The group travels through the dangerous woods and makes it to a bean field to rest. In the morning, Violet is killed by a hawk, leaving the group without a female. After several dangerous situations, they meet the enigmatic rabbit Cowslip, who invites them to his warren. They are grateful, but Fiver senses something unsettling in the atmosphere, as well as the resident rabbits' overly resigned attitudes, and leaves. An irked Bigwig follows, and chastises Fiver for supposedly causing senseless tension with his instincts. Moments later, however, he is caught in a snare trap. Fiver attempts to get help from their hosts, but is ignored. Bigwig is freed after nearly dying. As Fiver reveals, the warren is fed by a farmer who snares rabbits in return for his food and protection from predators. After...

Movie plot title: Pacific Heights Movie plot: Carter Hayes (Michael Keaton) is in bed with a woman, Ann Miller (Beverly D'Angelo) when he is suddenly attacked and beaten by two men. After the men have left, Hayes tells Ann, "The worst is over". He says he is planning to head out and see his family. The scene shifts to San Francisco, where an unmarried couple, Drake Goodman (Modine) and Patty Palmer (Griffith), purchase an expensive 19th-century polychrome house in the exclusive Pacific Heights neighborhood. They rent one of the building's two first-floor apartments to the Watanabes, a kindly Japanese couple who have no children. Not long after, Hayes visits to view the remaining vacant unit and immediately expresses a desire to move in. Hayes drives an expensive Porsche and carries large amounts of cash on his person, but is reluctant to undergo a credit check. He convinces Drake to waive the credit check in exchange for a list of personal references and an upfront payment of the first six months' rent, to be paid by wire transfer. Before any of this money is paid, however, Hayes arrives unannounced one morning and shuts himself into the apartment. As days pass, Drake and Patty grow increasingly impatient when Hayes' wire transfer fails to materialize. From inside the apartment, sounds of loud hammering and drilling are heard at all hours of the day and night, however the door is seldom answered.
