What a scoop! An eccentric scientist is killed, and Lois is the only witness. But the murderer is determined that Lois won't live long enough to file her story.
Lois interviews an eccentric scientist, Vincent Winninger, and while the interview she witnesses his murder and also learns about a conspiracy that will destroy the environment.
When she publishes the story, Lois becomes a target for the people who murdered Winninger since they have to eliminate everyone who knows. Perry and Clark try to protect Lois from the killer while they all work together to find out who is behind the murder.
When they find out that the murderer is Sebastian Finn, aka Mr. Makeup, who can transform to anyone he wants, Lois is scared more than ever. With the help of Superman, they manage to find Finn and arrest him, as well as Barbara Trevino, the women who asked Finn to kill Winninger and also tried to kill Lois after Finn's arrest.
