In a reserved seat carriage of the Chelyabinsk-Moscow train, forty-year-old Gena and twenty-five-year-old Sanek, a young film director, meet. Gena is going to visit his dying grandmother in his native wilderness, and Sanek is going to the premiere of his film. Gena tricks Sanek into getting off the train with him. Hundreds of kilometers from Moscow, they spend an eventful day and a half until the next train. Gena introduces Sanek to the whole cross-section of his life: the history of his family, love, friendship. Thus, experiencing all the troubles together, Sanek and Gena become true friends. This chance meeting becomes fateful for Sanek, changes his worldview and determines the theme of his future film.
