Synopsis:
Superman and Flash both awaken in separate locations wearing the other's costume and without a memory of who they are. Superman wearing Flash's costume and possessing super-speed believes he is the Flash and returns to Central City. Meanwhile Flash discovers his own speed also, but cannot utilize the other powers Superman possesses. He does discover Clark Kent's id and clothes in his cape pouch. Using a plastic mask he assumes Clark's identity at the Daily Planet.

Superman, still believing that he is the Flash, reads about a planned meeting with the Man of Steel, so he races toward Metropolis. The Flash is having difficulty adjusting to the role of Clark Kent because he does not possess Clark's writing skill.

The two heroes then cross paths in a subway tunnel. They come to realize who they really are. Both were attacking an intelligent space seed that was threatening Earth. They switched costumes to confuse the seed, but they were thrown back to Earth in defeat. With the seed still threatening to land on Earth, the heroes combine forces to briefly stop Earth's orbit around the sun. The seed's trajectory misses the Earth and carries it into the sun.
