Sheriff Jess Roden is called in to bring his backwoods tactics to bear on a case that has defeated the city police, the murder of a man who had been sent to investigate an illegal still. Roden poses as a city slicker on a fishing trip, discovers several suspects all engaged in illegal activities- one hunts out of season, another dynamites fish, a third makes whiskey. They keep tabs on him, he must be careful not to arouse their suspicions, but in the end he gets the killer. For Cunningham fans.
