On a remote boat, surrounded by sharks, a serial killer carries out his gruesome ritual — until one woman begins to disrupt his perfect system. Spectacular and original shark horror full of humour, suspense and unexpected twists.

Tucker runs a seemingly innocent cage diving excursion for tourists, but beneath the surface simmers a deep-rooted obsession. To him, sharks are not monsters — they are pure, instinctive and honest. Unlike humans. In the endless silence of the ocean, he performs his own gruesome ritual.

When Tucker meets Zephyr — a rebellious surfer with a troubled past — he is certain she must be his next victim. On his deserted ship, far from shore and any form of help, he locks her up. But Zephyr throws Tucker off balance. She fights back. Not only with her body, but with something he cannot control: hope. When a man from Zephyr's past, Moses, tries to rescue her, Tucker is thrown off balance. Suddenly, not only is his ritual at stake, but also his conviction.
