This movie, Night Train to Lisbon, was based on the homonymous novel by Pascal Mercier and tells the story of a Swiss teacher, Raimund, who sees a young woman in a red coat standing on the railing, about to leap. Dropping his briefcase, he runs and pulls her down. She helps him gather the papers that have spilled from his briefcase and accompanies him to the school where he teaches. But instead of waiting to talk, she leaves in the middle of his class, leaving her coat behind. 
Raimund grabs the coat and runs after her, but in vain. He checks her pockets for identification and finds a small book, a memoir of sorts, by Amadeu de Prado. It is stamped with the address of the bookstore where he is a regular customer, and he goes there. The bookseller remembers the girl's purchasing the book and, as he leafs through it, a train ticket to Lisbon falls out. The train is leaving in 15 minutes so, Raimund rushes to the station, but the woman is nowhere in sight. At the last moment, he decides to use the ticket himself and jumps on the train. During the journey, he reads the book and, while in Lisbon, tries to find Amadeu de Prado to solve the mystery. The rest of the story? Well, you’ll have to watch the movie!
