ALAN is a demure, cold, cynical, but rational and resolute agent. He says he is from Boston, and that he is traveling by train from New Orleans to Chicago for business purposes.

RALPH, on the other hand, is an outgoing, lively, but often indiscreet salesperson. Unlike the former, the latter's life is full of surprises, and it turns out it hides shocking mysteries such as the deaths of his beloveds. First, his hippie girlfriend in the 70s gets strangled on a beach; then, his wife several years later, falls from a cliff and, lastly, a woman that he had met and desired, is found dead.

To worsen everything, Ralph suffers from severe amnesia that he associates to a road accident occurred years before. Ralph has forgotten his real name - that seems to be JERRY and not Ralph - and the people of his life. He is desperate to find an answer about his partners' killings.

Alan suggests solving Ralph's issues by employing the reasoning. Ralph trusts him and spills the beans, and they brainstorm ideas all night long on the train, but Ralph's memory appears to be utterly compromised. Alan believes that the assassin might be someone who begrudges Ralph for an obscure reason and supports his argument showing some Psychology knowledge.

The story gets a thrilling finale.
