A Newfoundland trawler fisherman is caught in a radioactive storm caused by aliens. When he returns to shore, he's a superhero. He wears a souwester and raingear, and he can fly. He carries a fishing net which he uses to entangle villains, then pummel them into submission with a radioactive codfish.
