Synopsis:
A meteor crashes on Earth containing a caveman. The caveman is from Krypton, kept in suspended animation for thousands of years. When he awakens, the caveman possesses powers like Superman and becomes a menace. Superman and Batman try to catch him but his powers allow him to escape.

A crook named Pete Waller dresses as the caveman and robs a jewelry shop. Batman catches him, but the real caveman rescues Waller believing him to be a friend. Waller and his boss use the caveman to rob a bank.

Superman, meanwhile, has created an area of land similar to ancient Krypton. When the caveman sees it, he thinks that he is home. The crooks use Kryptonite on both the caveman and Superman. Batman rescues them, and Superman catches the crooks. The exposure to Kryptonite combined with the cosmic rays he was exposed to during his journey, kills the caveman.
