Four Queens for an Ace
Hakim Gregory escapes from prison by killing a number of guards, and returns to his hide-out abroad, to lead again his gang of drug trafficking and contract murders. Layton of the Secret Service must discover, and arrest him. The difficult mission almost becomes impossible with the rivalry of Layton's partner, Petula, the jealousy of his bride, Marion, the possible treachery of a Spanish woman, Dolores Arrabal, and yet a mysterious and sexy informant, Rosario... Too many women for Layton.
