 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 outgunned, 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?
