A womanizing policeman with a tendency for violent arrests quits the department rather than face an inquiry. He is recruited by a defense lawyer to assist with the murder trial of a young beautiful foreign widow whose older rich husband was killed. The wife and her playboy boyfriend are the defendants and the ex-cop is assigned to check out their alibi including a dubious witness. There is a larger criminal conspiracy underway and the relationship of the suspect and her husband and his murder get swept up in the cover up of the real crime.
