 After several unsuccessful raids, Wilcox County Sheriff Barney Bishop enlists the aid of Dan Mathews in closing down Al Sandy s Club Bahamas, the site of an illegal gambling casino. Another raid is unsuccessful, even with the aid of Dan and his officers. However, they learn that the activity takes place behind two sets of doors and that very little advance notice is needed for Sandy and club manager Ollie Dyer to be able to squelch the activity and conceal the gambling tables and equipment. Dan assumes the identity of a heavy-tipping businessman and has Sergeant Corey pose as a telephone repairman in order to position themselves to control all of the doors when the next raid takes place.
