Your favourite gamer trio is back! This time, Waldek, Staszek and Delfina will spend an adventure-packed summer in the Tatra Mountains. During the trip, Waldek accidentally finds out that his father – the man he has heard so much about from his mum, the person who abandoned his family a long time ago – lives nearby. The boy is determined to find him and ask him about the reasons for his decision. Together with Staszek, under the cover of night, they set out on their mission. The hazards of the mountain trail, however, are nothing compared to what Delfina will have to do. The creative teenager has to hide the truth about the boys’ disappearance from her aunt, the mother of Waldek and… her new partner. How will this secret mission affect the lives of all the characters? Will Waldek find an answer to the questions that haunt him and understand the actions of his father?

In 1954, a German-Austrian expedition led by Mathias Rebitsch set off for the difficult-to-access Karakoram Mountains, geographically north of the Himalayas. They come across the Hunza, a people who live in the valley of the same name and believe they are descended from the soldiers of Alexander the Great. The documentary conveys impressions of the poor life of the Hunza people, the harvest, a court hearing, festivals and the children's everyday school life. Finally, the expedition sets off again and sets up its main camp on the moraine ridge of a glacier, where they measure the glacier and the earth's magnetic field. Finally, some men from the research community set off for a sub-peak of Batura.
