A father who experiments with his son's psychokinetic powers is unaware that these experiments have released a demon from hell which lives in his son's closet, preparing to take over the young boy's soul.
At Camp North Pines for Boys, the campers, led by the charismatic Franklin Reilly, stage a revolt against the strict owner, Mr. Warren, and lock him and the rest of the counselors up and take over the camp for themselves. But the revolt soon spirals out of control as the boys also lead a takeover of the nearby girls camp as well. Then, Mr. Warren is accidently killed trying to escape. Soon friction happens between the two boys and girls camps, while one camper, a certain Donald Poultry, tries to get the word out and unseat Franklin as the leader.
