Doomwatch

The mysterious village of Balfe is experiencing unexplainable phenomena from grossly oversized sea-life to half-buried bodies in the dark woods to strange Neanderthal-like men suffering from a rare disfiguring disease. Is this town afflicted by radioactive waste contaminating their water? Is there a vengeful mutant monster lurking in the woods? Or worse, are the townsfolk being punished by an act of God for their past sins? Starring George Sanders in a supporting role.

Doctor Del Shaw is sent to the island of Balfe to file a report on the effects of a recent oil tanker spill. Investigation shows that the villagers have been suffering over a prolonged period from hormonal disorders. The islanders have been eating contaminated fish and develop a disorder of excessive hormonal growth which produces aggression and eventually madness.
