John Graham, a World War II veteran and head of the Foreign Office cypher group, seeks revenge on the driver and passenger of a hit-and-run automobile that struck and killed his pregnant wife, Carol. The two people in the car (Mickey and Lorna) were fleeing a robbery when they heedlessly ran over Graham's wife. Graham takes a leave of absence from his job so that he can track down and kill the hit-and-run couple. He winds up killing both of them in a fit of rage, running his car over their bodies multiple times. When the police catch up with Graham, in the original script, he commits suicide by drinking poison, but the British censor forced Hammer to rewrite the film's ending so that the poison does not kill him, and he is led away to prison. Still the censors were not happy with the amount of vigilante violence that remained in the final cut of the film.
