Events of the film take place in both hemispheres. Presidents of countries, bosses of drug cartels, special agents and powerful secret service agencies from all around the world are the first hand participants of its events. The film begins with an account of a shocking yet quite ordinary skirmish - an average drug kin pin is beating one of his assistants with a golf club with a purpose of educating him, because the assistant's cell phone was quite unlawfully confiscated by an overly diligent secret service agent. The mutilated gangster understands the incommensurability of his guilt and the level of his fault, and becomes the first character who asks the question: What do we know about the world we live in?

Investigating the murder of a resident of the suburbs Louis Touré, Maigret faces the indifference and cruelty of the people surrounding Louis in recent years. The diagnosis and the verdict — all guilty.

A divorced Professor of gynaecology leads a quiet life preferring his work and his own company to other people. However, his solitude comes to an abrupt end when a neighbour knocks on his door one day asking for help. A young girl in his office is pregnant. Alone and confused, Anna feels that an abortion is her only option, but her doctor has advised her that, if she goes ahead with the operation, it is unlikely she will be able to have children. The Professor reluctantly agrees to examine her, but when he confirms his colleague's diagnosis, Anna is distraught.

The characters of the play do not know that tomorrow there will be a war, that many people have only a few days left to live. They enthusiastically fight with the teacher, fall in love, cry and laugh, have fun, fight, mischief and impudence, but they seem to be just children, although - the paradox of that time! - their souls mature and develop much faster than their bodies. And when their friend's father is arrested by slander or mistake, they are ready for the first trials, for the initial lessons of injustice and grief, mutual assistance and mutual understanding. The tragedy that happened in the classroom was a kind of test of readiness for tomorrow's sacrifices and tomorrow's exploits.

Based on the play of the same name by A.N. Ostrovsky.
