A bachelor party in the Caribbean takes a horrifying turn when a group of friends decides to explore a supposedly deserted island. What begins as a night of fun and celebration quickly spirals into terror after they stumble across a secret medical facility hidden deep within the island. Inside, experiments have unleashed a deadly, flesh-eating contagion that cannot be contained. With no way to escape and the very water around them carrying the infection, the group must fight to survive as the virus spreads at an unstoppable pace. Serving as a prequel to the Cabin Fever series, Patient Zero reveals the origins of the gruesome outbreak that started it all.
