Synopsis:
Perry White receives an award honoring him for 25 years of service to the Daily Planet. Perry's friends and colleagues each sign the plaque. A short time later, Clark Kent goes berserk and tries to kill Perry. As Superman he has no memory of his actions, but each time he becomes Clark, he tries to kill Perry again. Eventually Superman discovers that a Kryptonian artifact has made him sleepwalk. Clark's real target was not Perry himself, but the signed plaque hanging on the wall. Clark subconsciously realized that his signature and Superman's were close together on the plaque, and the handwriting was the same. To protect his secret, Clark destroyed the plaque. He then tries to explain his actions as having been hypnotized by a criminal.
