There's a germ of a good exploitive drive-in movie here - teenagers stranded on an island getting into sex games, then fighting drug smugglers who arrive and threaten to kill them. It might have worked had it not all been presented in such a dull and unimaginative way - as well as if the teenagers were a likeable bunch that we cared about. It doesn't help that the movie was severely cut up before its release (look at the running time), with a narrative device added to explain things that not only doesn't explain much, but is pretty annoying.
