The show opens with a P.A. announcement welcoming a busload of new guests to Camp Karefree, a two-week summer camp for adults in the Catskills. Camp host Lou Kandel gives the newcomers, mostly women, the rundown of the place; first, he introduces the waiters, mostly college men. Then he tells everyone the two rules - Camp Karefree cares for you, and when the lights flicker the girls go to the girls' side and the boys go to the boys' ("Camp Karefree Song").
