"Black Bill" is the name of the legendary shooter they tell stories about around campfires in the Wild West. And Freddy Quinn plays the singing Robin Hood of that Wild West. The black-clothed avenger rides through the prairie in search of bad guys, whom he shoots willy nilly in his self-imposed quest to protect innocent settlers in a lawless land. But before he took to the range in his black mask, terrorizing poor bandits looking to make an honest day's living, Freddy grew up on the farm of Old Ted, after a murderous band did in his parents. Since then, the singing killer's vowed to get his revenge by gunning down any criminal he sees. One day, Old Ted's kidnapped by bandits looking for the secret location of a goldmine ... and they're prepared to use torture to get the information (including making the old man listen to some of Freddy's singing, if need be). When Freddy finds out what's happened to Old Ted, he rides out to track down the bandits.
