The film tells about the champion of the USSR, Europe and the world in trampoline jumping Olga Starikova. The athletes are training in Togliatti with coach Vitaly Aleksandrovich Groisman, and the champion in acrobatic jumps on the track Nadezhda Masloboishchikova is training there. In 1973, the first international trampoline jumping competition for the prize of pilot-cosmonaut G. Dobrovolsky was held in Moscow, where Olga defeated the American Alexandra Nicholson for the first time.
