In prohibition-era Chicago, the corrupt sheriff and Guy Gisborne, a south-side racketeer, knock off the boss Big Jim. Everyone falls in line behind Guy except Robbo, who controls the north side. Although he’s out-gunned, Robbo wants to keep his own territory. A pool-playing dude from Indiana and the director of a boys’ orphanage join forces with Robbo; and, when he gives some money to the orphanage, he becomes the toast of the town as a hood like Robin Hood. Meanwhile, Guy schemes to get rid of Robbo, and Big Jim’s heretofore unknown daughter Marian appears and goes from man to man trying to find an ally in her quest to run the whole show. Can Robbo hold things together?

Jim Slater’s father (whom he never knew) died in the Apache ambush at Gila Valley, and Jim is searching for the one survivor, who supposedly went for help but disappeared with a lot of gold. In the process, he gets several people gunning for him, and he keeps meeting liberated woman Karyl Orton, who may be on a similar mission. Renewed Apache hostilities and an impending range war provide complications.
