Opening narration
Plot
Carl Lanser is a passenger on the S.S. Queen of Glasgow, an isolated British cargo liner crossing the Atlantic in 1942, but has no idea of how he got aboard or who he is. Sitting with the captain and several passengers, Lanser dismisses fears of the ship being hunted by a U-boat "wolfpack", saying only one U-boat would be necessary and it would not bother using a torpedo on the ship. He is unable to explain how he knows any of this and recalls only that he was born in Frankfurt, but says that he finds the ship, its crew and passengers oddly familiar. When called to the bridge by the captain he cannot provide proof of his identity. Still confused, Lanser is sent back to his cabin with a steward, where he finds a Kriegsmarine officer's cap among his possessions with his name written on the inside.
The captain is forced to stop the ship for repairs when the overworked engines break down at 12:05. Lanser becomes increasingly restless, haunted by an inescapable sense of impending doom. Convinced that everyone aboard the ship will die at 1:15, Lanser panics and runs through the passageways, attempting to raise an alarm. He finds the ship is mysteriously empty. When he finally locates some of the passengers, they silently stare at him as he implores them to abandon ship. At exactly 1:15, a searchlight illuminates the ship, and a surfaced U-boat, commanded by Captain lieutenant Carl Lanser, opens fire with its deck cannon and machine guns. The ship quickly sinks, leaving no survivors.
