The Chain Reaction is an Australian-made drama about a nuclear accident and its effect on the workers of the plant. Oates (Patrick Ward) knows of the accident and the eventual effects it will have on the workers and the surrounding community, and he tries to tell them but the owners of the reactor try to have him eliminated before he can do so. The cast includes Mel Gibson in an uncredited role as a mechanic. Also released as Nuclear Run, this thriller, with an intelligent script by Ian Barry, is worth a view.
