It was supposed to be a luxury cruise: a four day round trip from Galveston, Texas to Cozumel, Mexico. But for the 4,000 passengers and crew on board, the reality proves catastrophically different. After an engine room fire destroys electrical cables supplying the entire ship, the boat is left drifting with no power for propulsion, refrigeration, lighting, air-conditioning or... worst of all, flushing toilets. Soon raw sewage leaks out all over the ship, food supplies start dwindling and passengers begin to revolt. As the cruise company races to control the fallout, a media frenzy ensues. Soon everyone is talking about 'The Poop Cruise'.
