Synopsis:
Batman and Robin discover a man collecting Kryptonite. They are unable to stop him, but learn that the man is a time traveler from the future. Batman contacts Superman, then pursues the man into the past using the time machine of Professor Nichols.

Superman pursues the man into the future, where he discovers the man’s twin brother John Durr, the inventor of the time machine. The assistants of John’s brother Rak capture Superman with some Kryptonite and wait for their leader’s return.

Batman and Robin are unable to stop Rak in the past, as the crook steals a meteorite fragment fashioned into a hammer by norsemen. When Batman returns to the present, more Kryptonite is stolen, this time from the Bat-Cave. The Caped Crusader finally finds and defeats Rak, then travels into the future to rescue Superman.
