A based-on-truth movie about the life of Graham Young. Mr. Young is a person whose dreams were crushed when instead of creating a diamond with his chemistry set (which included some pretty lethal chemicals), his experiment blew up in his face. His parents were very harsh on him, and he seemed to be the scapegoat of the family. Mr. Young exacts his revenge on the world by poisoning his enemies. One of his first victims was his friend, who happened to have a date with the girl he liked. His friend did not die, but was very ill for a time. He poisoned both his stepmother and his father to death. After a stay in a mental institution, Mr. Young ends up poisoning some of his workmates. The awesome thing about this movie is that Mr. Young is not portrayed the villain, but more of a tragic hero, someone that the watcher can identify with and feel sorry for.
