The Deadly Little Mermaid
A struggling artist rescues a mysterious woman from the ocean, but soon discovers she's not what she seems, and there's no escape from the darkness she brings.
Some secrets are better left at the bottom of the ocean. Once she's in your house, there is no escape. When a struggling artist pulls a beautiful, unconscious woman from the freezing coastal waters, he thinks he’s performed a miracle. But as she recovers within the walls of his secluded home, a series of unsettling events leads him to a terrifying realization: her presence is no coincidence. She is inextricably linked to the same watery grave that claimed his family years ago.
