The Twilight Zone, Season 3

Narrator:
Picture of a man with an Achilles' heel, a mystery that landed in his life and then turned into a heavy weight, dragged across the years to ultimately take the form of an illusion. Now, that's the clinical answer that they put on the tag as they take him away. But if you choose to think that the explanation has to do with an airborne Flying Dutchman, a ghost ship on a fog-enshrouded night on a flight that never ends, then you're doing your business in an old stand in the Twilight Zone.
