The strains of Richard Wagner's operatic music and the tale of Lorelei, which an old man is telling his granddaughter, set the tone for this tense and highly symbolic crime thriller, which takes place on board the TEE Rheingold train travelling from Germany to Basel, Switzerland. The murderer, a highly sympathetic character, commits his fatal deed under high stress, which only increases when, after exiting the train, he realizes that he left incriminating evidence onboard. Now he must race in an automobile across Germany and attempt to reboard the train to recover the evidence before the killing is discovered.
