The story of a childhood dream come true. Schoolchildren discover an abandoned poultry farm with an artificial hatchery and agree to raise their own chicks. They devote all their energies to it and wait anxiously for the little chicks to come into the world. Before that happens, they face many obstacles...

Vladimír Olmer is a student at the Faculty of Medicine. His father, a famous Prague surgeon, is rightly proud of him. One day, Vladimír accidentally meets his former classmate Emil Prokeš. He introduces him to his frivolous friends, who only care about how to earn money for an idle life without any effort. The trusting Vladimír takes a liking to his new friends, especially when the beautiful Helena shows interest in him. Soon, parties with alcohol are more important to Vladimír than his studies. Mirek, his only real friend, warns him in vain. His frivolous life ends with a fateful party at which Emil is shot. The case cannot be covered up, the security services get involved, and Vladimír is expelled from the faculty for a year.
