Wacky hijinks of counselors and campers at a less-than-average summer camp.

Twenty years ago in the sleepy mining town of Valentine Bluffs, a fatal mining disaster occurred on Valentine's Day while some of the crew was decorating for a party. The sole survivor of the accident killed the remaining crewmembers and warned the town not to celebrate Valentine's Day again. When a group of teenagers decides to defy that order, a murderous maniac in mining gear begins dispatching townsfolk in bloody and creative ways.

A gay bar is hit by a group of sociopaths, and all the patrons are killed except for one man who escapes and takes refuge in an apartment occupied by a group of friends, who will do anything they can to protect him and survive the siege.

A decades-old folk tale surrounding a deranged murderer killing those who celebrate Valentine's Day turns out to be true to legend when a group defies the killer's order and people start turning up dead.
