In the film, a group of nudists is forced off their land by religious zealots, and then commits mass suicide.

"Sunny Buttocks Nudist Colony" is shut down by Judge Rhinehole and his band of religious zealots for offending the local community.

The nudists decide to protest by entering into a suicide pact, vowing to return one day to terrorize the people who took over their land.

True to their promise, the nudist corpses rise from the grave, seek revenge on the zealots who condemned them, and sing big production numbers as the campers begin to experience an attrition problem.
