Tragicomic family film about the world of children heroes - particularly the son of a local communist officer and his friend, a little hostage of the regime, whose parents emigrated to the West, few years before "Prague Spring" and the occupation of Czechoslovakia. Camaraderie, the first big discoveries of love, enemy gang fights and naive ideas are confronted with the reality of adult's world. The film is about the first contacts with bizarre and absurd reality of relationships and attitudes of adults, politics, emigration, but also betrayal and death and about how all those things form and transform the lives of small boys, who are forced to grow up too quickly.

Petr is a courier, a messenger as a matter of fact. He is one of those young men who believe that on their bikes they have become part and parcel of the atmosphere of modern cities. He is a non-conformist who refuses to settle into today‘s deformed society, he abhors its indolence, consumerism and lies, as well as its pseudo-truths, pseudo-feelings, pseudo-loves and pseudo-values. Petr’s untrammelled personality keeps causing more and more serious problems. And Petr is also one of those who will never admit to themselves that they might be at the end of their tether.
