Young Rap Brender had left home after a quarrel with his father. When the old Judge asks Arizona Jim Silver to find his son, the legendary Silvertip agrees because Rap has joined the gang of Barry Christian, the outlaw king and Silvertip's sworn enemy.
Silvertip's search for Brender leads him through towns totally corrupted by Christian's evil genius, to a desert oasis transformed into an outlaw paradise. Here Silvertip finds Brender. He continues to pursue Christian across smoldering desert sands and into icy mountain passes. It is a chase that can end only in death, for Silvertip and Christian have vowed to make this their final clash.
