Achilles Heel

17-year-old Susanne is a gymnast and has a chance to join the national team. But now, of all times, she is having problems in training. She can't manage the new dismount from the uneven bars. At the same time, she gets into other conflict situations: her performance at school is getting worse. Her ambitious mother, accustomed to her daughter's successes, does not show the necessary understanding. Her father, divorced from Susanne's mother and constantly traveling, is rarely there for her. Her boyfriend Michael, with whom she experiences her first love, soon has to join the army and feels neglected because Susanne has too little time for him. Her coach, however, shows understanding and stands by her side in conflict situations, which she eventually overcomes - and so her success in sport returns.
