Two young women and a young man confront a tech mogul on a train about their new invention.

A train travels across Italy toward Rome. On board is a professor who daydreams a conversation with a love that never was, a family of Albanian refugees who switch trains and steal a ticket, three brash Scottish soccer fans en route to a match, and a complaining widow traveling to a memorial service for her late husband who's accompanied by a community-service volunteer who's assisting her. Interactions among these Europeans turn on class and nationalism, courtesy and rudeness, and opportunities for kindness.
