Soon after a group of scuba divers finds a dead body adrift in the ocean, they lose their own boat and are forced to take refuge in a nearby merchant vessel. Unfortunately for them, the ship's crew and the killers are one and the same -- and they'd like nothing better than to purge their human cargo. Can the divers survive as desperate stowaways, or are they destined to die? Lluis Homar, Silke, Adria Collado and Unax Ugalde co-star.
