A group of teenage boys are tricked into accompanying their teacher on a survival holiday to a deserted island. But when the teacher suffers a nervous breakdown and turns hostile, the boys are forced to fend for themselves.

A young boy dies after swimming at a seaside resort, and the local children, led by Gavin, investigate and are led to suspect that contamination from a nearby nuclear plant is to blame. Their teacher is sympathetic, but has broken into her house, perhaps as a warning. Gavin is nearly killed after talking about the problem on TV, but gradually all is uncovered - with terrible consequences for Gavin.

A gang of boys who run their money raising 'business' - on strictly free market lines - is threatened by the arrival of another group. - A socialistic group, headed by a black girl!
