RKO's Bunco Squad stars Robert Sterling as Sgt. Steve Johnson, a big-city detective dedicated to tracking down con artists. His current target is a gang of slicksters who are running a successful seance racket. Wealthy Jessica Royce (Elizabeth Risdon) is on the verge of bequeathing her fortune to the crooks, in exchange for communications from her deceased son. Posing as a couple of "marks," Johnson and girlfriend Grace Bradshaw (Joan Dixon) turn the tables on con-man Anthony Wells (Ricardo Cortez) and his confreres. On hand to reveal some of the techniques used by bunco artists is Dante the Magician, aka Harry A. Janssen, making the second of his two screen appearances (the first was in Laurel & Hardy's A-Haunting We Will Go).
