It's a blistering hot summer. Maciej Kornet is traveling around Poland with his 17-year-old daughter, Wiktoria. It's been only the two of them for years, always together. The route they take is determined by where tennis competitions are being held. She is the apple of his eye, while he's her entire whole world.

A caring daughter, a laid-back mother, a popular teacher, a wife you are thick as thieves with – Joanna – is outstanding in each of these roles. But in none of them does she feel like herself. That is why she leads a double life. She has a secret she shares with no-one.
