In one scene the mother gets Thomas out the bathtub for drying and dressing him (full nudity). After that the other 2 older boys leave the bathtub. Short rear view of Sascha and partial side view of Jonny.
Ulla (Stefanie Stappenbeck,16) is swimming naked in a creek and was spied on by Winfried (Cornelius Schulz, 17?). She got up and covered herself with a towel. At one point it slipped, revealing her nake body again (view is distant).
