Aggressive Bill Harper, with his bride in Miami, goes to the defense of a former girl friend when the murder of a seedy socialite implicates her beyond a doubt. Suspecting the dead man's tie-up with a professional gambler, Harper calls his long shots, some rose petals scent the trail, an I.O.U. saves a reputation but loses a motive, and it is the police who secure his solution for him. More voltage than vintage.
