Juan is an elderly man returning home by train who meets a young woman on the journey and strikes up a conversation with her. The conversation revolves around his profession as a railway worker and the landscape through which the train travels, but above all, Juan talks about love: love for his wife, for the life he has lived, and for commuter trains as a place for meeting and conversation, because there was a time when the important thing about the journey was not the destination, but who was traveling beside you.
