Simon Wells, American visitor to Britain, picks up a girl on the Weymouth Promenade who turns out to be a decoy for a teddy boy gang led by her sadistic brother, King. He is beaten up and robbed, but is found by two army security officers from a secret project near the town and, on being taken to a hotel to clean up, meets Bernard the scientist in charge of the project, and his girl friend Freya, a beautiful sculptress who occupies a cottage built into the cliff nearby.
The next day, the girl, Joan comes to see Simon, and when the gang follow her she goes out to sea on his boat. They land along the coast and go to the cottage to hide from the gang. After dark they leave and are chased by the gang. Going over the barbed wire surrounding the secret project headquarters, they and King fall over the cliff into the water. All three are rescued by a group of children – eerily cold-blooded, who take them to their quarters, carved out of solid stone in the cliffs. Bernard, knowing the children are radioactive makes desperate efforts to get the adults out, but they misinterpret his motives and escape with the children through an entrance to the caves in Freya’s cottage.
