Synopsis
The Deadly Little Mermaid
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…
The Devil's Mouth
Five college friends set off to explore the Devil's Mouth cave system in Thailand for one last adventure before life in the real world begins. But they soon discover that something is hunting them under the water… fast, silent, and deadly. In the suffocating darkness, trust erodes, panic spreads, and every wrong turn becomes a fight for survival.
