The film begins with a symbolic scene: three Red Guards from the time of the revolution are walking down the street. The time of action imperceptibly changes, and instead of the Red Guard patrol, the audience sees their contemporaries - young people, and then - a soldier transferred to the reserve. This is the main character Sergey Zhuravlev.
