Frank Walsh (Cage), an expert big game trapper, has just boarded a Greek shipping freighter with a fresh haul of exotic and deadly animals from the Amazon, including a rare jaguar. However, the big cat isn’t the most deadly creature on board. Richard Loffler, a political assassin being extradited to the U.S in secret, is also along for the ride. Two days into their journey, Loffler escapes the team of U.S. marshals guarding him and releases the captive animals, throwing the ship into chaos. Frank must now find a way to save the crew from not only the dangerous beasts aboard, but also the madman on the loose.
