Synopsis:
Two members of the future Time Patrol return to the 20th century from the year 4069. They meet Batman and show him that Superman went mad after a failed experiment involving Red Kryptonite. The Man of Steel sent a super-satellite into the future which caused the people their to devolve into ape men. Batman accompanies the Time Patrol officers into the future to confirm their story.

After Batman has seen the truth for himself he returns to the 20th century and apprehends his friend. He brings the Man of Steel before a council of U.N. representatives. After testimony is given, Superman is found guilty. As punishment the Time Patrol officers plan to lobotomize him.

Before they can execute their plan, Superman exposes them as Luthor and Brainiac. Their story was a fake which was backed up a future remake of the Planet of the Apes movie. Batman only witnessed a movie set on his trip to the future. With the villains exposed, Superman is honored by the U.N. council that convicted him.
