A peaceful seaside village is shocked by a sudden and vicious double murder. The murdered men are a petty thief and a taxi driver.

A beautiful young actress informs the police that she saw the dead man's taxi and the man who stood beside it. The newspaper reports that she is potentially able to identify the killer and although the police provide her with protection, the 'Dark Man' strikes and leaves her for dead.

The police decide to transfer her to a secret location but is it secret enough to protect her from him?
