A luxury cruise turns into a nightmare when a mysterious infection spreads through the massive ship, transforming passengers and crew into ravenous undead monsters. As the living are hunted through the decks and corridors, a small band of survivors must fight their way to the bridge to send a distress signal. But the way is blocked by hordes of the bloodthirsty infected. Martin, the reluctant leader, Sandra, a deadly martial artist, and Marco, a crack marksman, form the core of the group trying to escape the doomed vessel. With makeshift weapons and dwindling supplies, they battle their way through a hellish gauntlet of unrelenting violence and shocking depravity. The constant threat of being torn apart hangs over them as they confront not just the infected, but their own fracturing sanity and moral restraints in the face of overwhelming horror. In this visceral and uncompromising tale of survival at all costs, no one is safe as the fight to live turns even the strongest into soulless animals willing to commit the most depraved acts to endure.
