An outsider visits a remote isolated village that has seemingly shunned modern life. Dr. Del Shaw, an investigator from the British ecological watchdog group nicknamed Doomwatch, is sent to the island of Balfe to file a report on the effects of a recent oil tanker spillage. He becomes fascinated with the mysterious behavioural disorders of the locals who display rudeness and random aggression and a strange genetic prevalence of thick lips and sloping brows. Investigation shows that the villagers have been suffering over a prolonged period from hormonal disorders, which are being caused by leaking drums of growth stimulants that have been dumped offshore. The islanders have been eating contaminated fish and develop a disorder of excessive hormonal growth, which produces aggression and eventually madness, attributed to a form of acromegaly. Rather than seek help from the mainland, they hide those who are deformed from any newcomers.
