Opening Narration
Narrator: Her name is the S.S. Queen of Glasgow. Her registry: British. Gross tonnage: five thousand. Age: indeterminate. At this moment she's one day out of Liverpool, her destination New York. Duly recorded on this ship's log is the sailing time, course to destination, weather conditions, temperature, longitude and latitude. But what is never recorded in a log is the fear that washes over a deck like fog and ocean spray. Fear like the throbbing strokes of engine pistons, each like a heartbeat, parceling out every hour into breathless minutes of watching, waiting and dreading. For the year is 1942, and this particular ship has lost its convoy. It travels alone like an aged blind thing groping through the unfriendly dark, stalked by unseen periscopes of steel killers. Yes, the Queen of Glasgow is a frightened ship, and she carries with her a premonition of death.

Lieutenant Mueller: I just, I just found it difficult to …
Lanser: To what?
Lieutenant Mueller: To reconcile the killing of men and women without any warning. Makes me wonder if we're not damned now.
Lanser: In the eyes of the British admiralty, we most certainly are.
Lieutenant Mueller: I mean, sir, in the eyes of God.
Lanser: Oh, you're not only a fool, Lieutenant, but also a religious fool, and perhaps a mystic at that. Suppose we are damned. What will happen then?
Lieutenant Mueller: I have had dreams about it. Perhaps there is a special kind of hell for people like us. Perhaps to be damned is to have a fate like the people on that ship, to suffer as they suffer and to die as they die.
Lanser: You are a mystic, Lieutenant.
Lieutenant Mueller: We'll ride the ghost of that ship every night. Every night, Kapitan, for eternity. They could die only once, just once, but we could die a hundred million times. We ride the ghost of that ship every night. Every night for eternity.

Lanser: It's here! That's the U-boat out there! The U-boat's here! We've got to get out of here, everybody! We have got to leave this ship! Everybody, they're going to sink us! Don't you hear me? Have you all gone out of your minds, all of you? There's a U-boat here! It's going to sink us! What do I have to do to you? Do I have to grab you and put you on deck? Do I have to grab your body and put you into lifeboats? Do I have to knock you unconscious all of you?!

Captain Wilbur: And they're out there. God knows, they're out there. Waiting, like vultures.

Closing Narration
Narrator: The S.S. Queen of Glasgow, heading for New York, and the time is 1942. For one man, it is always 1942, and this man will ride the ghost of that ship every night for eternity. This is what is meant by paying the fiddler. This is the comeuppance awaiting every man when the ledger of his life is opened and examined, the tally made, and then the reward or the penalty paid. And in the case of Carl Lanser, former Kapitan Leutnant, Navy of the Third Reich, this is the penalty. This is the justice meted out. This is judgment night in the Twilight Zone.
