Boys take shower after training.

Boy (Vojtěch Kotek, 13) and girl (Hana Kusnjerová, 16) undress to go skinny-dipping in a forest lake. Both seen nude from rear.

Rear nudity of Dany (Vojtech Kotek, 17) during shower scene. After Honzík swapped the signs of the showers an older lady walks into the shower where Dany is still taking a shower. He tries to sneak out, which doesn't work because a group of girls just came into the dressing room. He then tries to escape trough a small barred window, wearing only a towel. Which doesn't work, because girls enter the shower and his friend stops helping him.
