In Labyrinth, Texas, Rick Hartman needs help and sends for Clint. When he arrives, he finds his friend in jail, charged with the murder of the woman he'd been sleeping with. Clint also finds that Labyrinth has begun to grow in his absence, adding a red light district that is now filled with competition for Rick's Saloon. Certain his friend is not guilty of murder, Clint is convinced someone is framing him in order to close down his saloon and gambling hall, thus getting rid of the biggest place in town. Clint has to deal with an ineffective lawman, a crooked judge, and a red light district filled with possible killers in order to prove his friend innocent before he can be tried, convicted and executed.
