A billionaire heir, murdered by his own kin and dumped into the deep sea, is picked up by a gorgon from the forbidden ocean zone. After suffering a head injury that leaves him with the mind of a three-year-old, he calls out to her in a childish lisp, "Mommy". The gorgon had intended to kill him, but softens at the sound of that word and takes him in. When he regains his memories and falls in love with her, she personally escorts him back to the shore, turning all his betrayers to stone for him.
