Bailey Lotter is the black sheep of Leigh, or so say the townsfolk. Each year, the day before his birthday, himself and three other randomly selected people have to partake in a gruesome act to prevent a curse from striking the farming community he lives in. On the eve of his 21st, Bailey has had enough of the superstitious lot. But when he fails to go through with the ritual, an unimaginable terror does indeed menace the population. It's up to Bailey and his friends to banish the threat that stalks the streets in the night, before they hang for their folly.
