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).
Among other scenes near the beggining of the film students both male and female from around 15 to 16 and younger skinny dip together in the outside pool.
