Bank teller Mike Donovan (Barry Sullivan) takes the first step on the road to Perdition when he fails to report a $49,000 shortage. Accused of theft, Donovan is fired from his job. He is then prevented from finding other employment by Javert-like insurance investigator Gus Slavin (Charles McGraw). Despite many setbacks, Donovan holds out the hope that he'll be able to clear his name, but even his loyal wife Ruthie (Dorothy Malone) doesn't believe this will ever happen. Filmed on location in Los Angeles and Malibu, Loophole nevers loosens its grip on the viewer for a single second.
