In an instant, the cruiser swamps Paul and the young girl beside him, then disappears into the fog, never to be seen again. Dumped into the winter ocean, the terrified girl thrashes in the ice-cold water, submerging Paul in her frenzy to survive. In a desperate attempt to save them both, Paul makes a fateful decision.
