Responding to a distress signal, fishing-boat captain Brian Hawkins arrives in time to save the ship's last survivor. But the nightmare is just beginning. A casino cruise ship carrying high-stakes passengers -- and a top-secret cargo -- becomes the creature's bloodsoaked hunting ground. Desperate but determined, Hawkins goes after the biggest catch of the century.
