An actress is the witness to a murder and then the murderer comes after her whilst a policeman is looking for the killer and also develops affection for the actress. The plot for this British crime thriller is not entirely convincing, given he ruthless kills two men and then when he ha sthe opportunity to kill the actress he does not and then stalks her. It does however create suspense in parts of the film and ther is good use of both sound effects and music to enhance the atmosphere.
