Three youngsters have to take command of a space flight when their adult captain comes down sick and is forced to quarantine himself.

Having failed to enter the institute, Sergei got a job in a workshop to refill lighters. Giving all his free time to his new hobby - boxing, the hero in a short period of time achieves significant success and insists that the coach allowed him to the nearest competition. Having received a well-founded refusal, Sergei goes to another club and wins a victory over a famous boxer at a tournament. But the accidental victory does not bring him joy.
