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.
