Dean and Mike's first job is to help a mysterious femme fatal named Gloria Lake who fears her wealthy husband is plotting to swindle out of her inheritance. But before that can happen, the husband is murdered, and Dean and Mike are the suspects. With a relentless police detective tailing them, Dean and Mike try to solve the case, while dealing with the Devil's agent who follows them up from hell to bring them back within 46 hours.
