Superman receives a distress call from the future. He travels through time and meets Craig King, the Superman of 2956. King has become Superman using inventions of several scientists. However, he has been unsuccessful in stopping a crime ring.

Superman replaces King and tries to stop the criminals. He is also plagued by Lyra Lee, a future version of Lois Lane. Superman eventually exposes one of the scientists responsible for King’s powers as the criminal leader. After rounding up the crooks, Superman returns to his own time.
