The Girl on the Diving Board(1967)

The 18-year-old Katharina Jens is a high diving champion and succeeds in everything she does. When she enters an international contest in place of her team colleague Claudia, expectations are accordingly high. However, when she misses the one-and-a-half somersault with a double twist her team fails to gain victory. Suddenly, the question arises if she is in fact good enough.
