The boys of Class 3C buy a luxurious and enormous apartment for a paltry sum. Naturally, none of them questions why such a large house costs so little. Soon, the boys discover the reason: the house, which once belonged to a magician, is haunted. The boys, in turn, are mysteriously kidnapped by Igor, the deceased magician's assistant, who aims to own the apartment. Unmasked, however, Igor ends up working as a butler.
