With the help of Scott Mary, as he was named by Talby, Talby quickly takes over the town, but Scotts fast draw has now become a threat to him. After he kills Scotts former mentor, the two decide to settle things in a shootout. Scott kills Talby in a duel and all of his gang by taking advantage of the rules Talby once taught him. ........
