Mario Roccuzzo guest stars as Joey, a reformed alcoholic. As a personal favor to his friend, undercover cop Tony Baretta (Robert Blake), Joey pretends to fall off the wagon. It is all part of a scheme to get the goods on Joey's former boss, a blackmailer/pornographer/pimp who sidelines in murder. Onetime Bonanza star Pernell Roberts makes quite a meal of his supporting role in this episode. ~ Hal Erickson, Rovi
