The First Turn-On! on AllMovie

In this standard story of sex at summer camp, four campers are trapped for awhile in a cave and begin to fabricate supposedly true tales of their past sexual exploits -- giving rise to several flashbacks as their imaginary adventures unfold one by one. Even the nature-studies counselor who is trapped with them gets in on the act and relates a bizarre story when it is her turn to contribute. As time goes by and no help seems to be on the way, the group -- virginal to the core -- begins to wonder if their lives will end in that unwanted state.
