But is it just a comic book? Are secrets hidden inside this comic that can change the laws of science? When math wizard Harold sets out to crack the code, he finds himself in the fantasy world of Commie spies and creatures from outer space who threaten the American way of life. Joining Harold in this fight for freedom is the girl he has always longed for, the beautiful Becky. But she has fallen into the clutches of the high school bully Steve. Can Harold overcome his fear and discover the secret in time to save Becky and the world? Just when all appears to be lost, Harold realizes that he must be the hero!"
