A hot summer. Maciej Kornet (47) and his beloved daughter Wiktoria (17) set out on another journey across Poland. They are up for a long series of tennis tournaments. The two are inseparable; they have been training together for twelve years. Wiktoria meticulously follows her dad's routine: a strict diet, exhausting workouts, 100% focus. She is growing tired of this and longs for some freedom. She thinks of quitting sports but is afraid to hurt her father's feelings. This summer, Maciej's new trainee Igor (17) joins them on their way. Wiktoria will find the secretive boy much more interesting than tennis, and Maciej will have to watch his own dreams and his daughter's plans go separate ways.
