The Fisherman of Space was a massive demonic looking creature created in prehistoric times out of cosmic gasses. He was very sensitive about his appearance and bored with immortality he began to gather the most intelligent and strongest specimens from the human race throughout history to serve him on the Island of Lost Souls. The island was protected by a never-ending storm which prevented the Fisherman's prisoners from escaping and mysteriously also from aging. The Fisherman lives in the island's volcano and only left his home to gather more prisoners. However two captives, Inspector Haversham and Sir Cyril Bentley, used a radio in one of the downed planes to contact help from Dr. Crandell who instructs the US Military to drop dry ice and Sodium iodide on the Fisherman. Because he was made of clouds the chemicals cause him to become rain destroying him and freeing his prisoners.
