Daddy-O is a 1958 B-movie starring Dick Contino. It was directed by Lou Place and written by David Moessinger.
Later at the club, Phil is arrested in connection with Sonny's murder; he is let off on probation, but is stripped of his drivers license. Phil quickly launches into an investigation into the murder, his first suspect being Jana. She denies any involvement, and joins Phil in his investigation. He follows the trail of clues to nightclub owner Chillas (Sonny's assailant), and Chillas's lackey Bruce, who runs the gym Sonny used to frequent. Chillas hires Phil as a singer under the alias of "Daddy-O".
Not long after being hired, Phil is beaten up by a couple of drug dealers who have mistaken him for Pete Plum, a pseudonym used by Sonny. Phil draws the conclusion that Sonny had been moving money around for Chillas, and that he had stolen some of the money and was killed as a result. Phil confronts Chillas with the information, and they confront one another in a liquor cellar. Phil manages to knock Chillas out, and soon the police arrive and arrest him and Bruce. The movie ends just as Phil is asked to sing.
