During an ocean dive, Miami gumshoe Tony Rome finds a woman's body with its feet encased in a concrete block and sets-out to solve the murder case.

Fur-trapper Shawn Garrett gets out of a horse-stealing charge in a small, frontier town by agreeing to buy the horse with a gold nugget. This nugget attracts the attention of a man named McCracken who, with his gang, secretly follows Garrett across the desert in the hope of finding the source of his gold. Garrett joins up with his partner, Jim Rainbolt, and together they manage to hold off McCracken's gang long enough to hide their gold before seeking refuge in the hacienda of a landowner named Gondora. Gondora soon finds out about the gold, however, and Rainbolt and Garrett now find themselves in a fight to save their gold and their lives as well.

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?
