Assigned to Bunko detail, Joe Friday goes after a swindler. The background of a career con man is discussed, and his current activities as a used car salesman. Wallace isn’t the salesman, but forged checks to car dealers. The ex-con is called in, and makes a good front at claiming to be going straight. He has been warned, the cops are doubtful, but can a convict go straight?
Time goes by, and Wallace is watched. Has he slipped up by claiming to have industrial inventions to sell back to the same company who already holds the patent? Other instances of scamming businesses are uncovered, and Wallace is identified in each as the culprit. The method of stealing identities is discussed. Using a recently deceased mans identity, he also gets the grieving family to pay on a bogus debt.
Friday goes into voiceover to tell the age old profile of a con man, their motives, how they work, and what to be alert for in recognizing one. More instances of victims are visited, and how they were swindled. Doing their own obituary watching, the cops soon set up a trap for Wallace. Join the suspenseful ride as the cops follow the money, and stake out their man to catch him red handed.
