Who would suspect that before the live telecast is over for the TV quiz show "It's a Living!" the hardest problem to solve would be, "Who killed Tony Fabrizi, the show's sponsor?" And why was he murdered? Was it for the now missing diamond bracelet he had brought for the commercial, or was he shot for personal reasons? Homicide detective Lt. Jim Slate, along with Amanda Maxwell, a little old lady amateur sleuth, discover that most of the TV show's cast had motives to murder the man - including his Italian wife with a fiery temper. Rounds of the fictional game show are actually played during the performance using members of the audience on stage as contestants.
