Tucker and Dale vs. Evil

Two friends decide to spend their vacation in a cabin lost in the woods, planning to drink beer and kill time fishing. Tucker is considered the leader of the two, since his buddy Dale has an innate inability to approach the opposite sex. When they casually run into a group of college students on a camping trip, Dale tries to approach the beautiful Alison, one of the girls in the group, but only manages to scare her. Soon after, the young woman has an accident and is rescued by the protagonists, who take her to their cabin. From then on, a series of coincidences and misfortunes lead Alison's friends to conclude that Tucker and Dale have kidnapped her and that they are, in fact, deranged serial killers planning to end all of their lives.
