 Lana Lang finds some poems from a secret admirer in the gravestone of her parents in the cemetery. Later, she meets the author, Byron Moore (Sean Faris), a weird teenager kept locked by his parents in the basement of their farmhouse. They believe the boy is abused by his parents, but soon they realize that he was the subject of an experiment of a laboratory of Luthor Corp, which made him powerfully evil and super-strong when he comes into contact with sunlight. Meanwhile, Martha Kent is invited to work as the assistant of Lionel Luthor, and she accepts the invitation under the reluctance of Jonathan Kent.
