Young married couple Eva and Jarda Tuma (Dana Syslová and Oldrich Vlach) do not have a place of their own and cannot provide for a baby. However, nature wins and Eva becomes pregnant. At the maternity hospital, she gives birth to quintuplets. This great occasion does not escape the attention of the local and international media. The authorities decide to help support the family. They set up a commission for the care of the quintuplets, headed by Drahoslav Svitácek (Otomar Krejca).
