15-year-old Sabine tries to do everything to become a champion in running.

Sabine is a teenager who dreams of becoming a top athlete. She studies in a high performance sports center, under the strict control of Gelewski, who she constantly criticizes for his training methods. Sabine only thinks about improving her marks at all costs, even competing with male athletes. As she seeks absolute control over her body, which she conceives as a motor of unlimited possibilities, she ends up nullifying herself and those around her. A body is not a machine. It has its mysteries, its weaknesses, and at any moment it can collapse.
