Sunday in September 1977, a celebration of the Miners Day. The old Hepnar is sitting at the cemetery and is recalling events from ten years ago. That time the representative of the ministry Barvír announced at the miners meeting that mining in the mines would decrease. He reasoned this decision by the fact the deposits of coal are almost used up. The boss of the mine and most of the miners protested. Barvír did not take their critical objections into account. He announced at the communist district meeting the closure of the business as the mine according to new economic principles did not prosper.
A group of children are investigating a chain of mysterious events during the seventies.

For the self-assured and superficial Dominika (Irena Svárová) the whole thing is just a momentary whim. When she leaves the work camp before everybody else, she doesn't even say goodbye to Zofie. The two girls meet again after the holidays as first-year students at medical school, and become close again during the nursing techniques class.
