在这部邪恶的午餐夫人喜剧/恐怖片中,瓦巴卡营地是一个为陷入困境的年轻人提供康复服务的中心，该员工刚刚增加了一个新成员：午餐女士。 当她开始谋杀违反规则的学生时，事情开始变得艰难。
Camp Wcabaca is a center for troubled youth, and is home to many eccentric staff members: Margaret, the fourteen year old camp director, Mark, the southern counselor, Samantha, the controlling counselor in training, and of course, the Lunch Lady. Five students arrive at the camp, each very different and unique. The Lunch Lady makes a rule that meat is not allowed on camp grounds. The students don't care about this rule, and it seems that every student that breaks the rule disappears from camp. Soon, it's up to two students to find out who is killing their peers.
