After escaping from an insane asylum, a medical student assumes the identity of a mysterious dead man, who appeared to be his doppelganger, and gets lured to a sinister island ruled by a mad scientist and his malformed men.

After escaping from an insane asylum, a young medical student takes on the identity of a dead man to discover the true identity of a man whose picture he saw in a newspaper--who is his exact double. His investigation leads him to a remote island where he discovers a sinister laboratory where a crazed scientist is performing gruesome experiments on live humans--and that his own family has a connection to the scientist.—frankfob2@yahoo.com

The medical student Hirosuke Hitomi is mysteriously interned in a mental institution without any explanation. When a stranger tries to kill him in his cell, he flees from the asylum and sees the young woman from the circus Hideko singing a lullaby that stays in his memory. She tells to him that she is from a coastal town, but out of the blue, Hideko is murdered. Hirosuke travels to the coast and learns in the newspaper that the wealthy Genzaburô Komoda, who is his doppelganger, has just died. He decides to assume his identity as if he had had only a sudden illness and revived. He lures his wife Chiyoko Komoda, his mistress, the butler and the servants. When mysterious letters are delivered to his wife, who dies, and his mistress, he decides to travel to the island where Genzaburô's father Jôgorô Komoda lives to find his origins. Soon he meets Jôgorô, who is a mad man that built an island of freaks, turning normal persons into malformed persons. Further, Hirosuke learns who he is.—Claudio Carvalho, Rio de Janeiro, Brazil
