As he often did in his 1970s TV appearances, Jackie Cooper forsakes his "good guy" image in this episode to portray a cold-blooded criminal. In this case, Cooper is cast as jewel thief Frank Mullvaney, who intends to pull off a heist at a jeweler's convention right under the nose of Lt. Kojak (Telly Savalas). Such an undertaking requires a disguise, and Mullvaney has a beauty: he's going to show up at the convention dressed as a priest. ~ Hal Erickson, Rovi
