Jan Kačer became known primarily as an actor, but he also took up film directing several times - not very successfully. Based on someone else's script, he made a committed, building story: it tells the story of an experienced engineer who is commissioned to assemble a team of specialists for engineering the peaceful use of atomic energy. However, the explanation of human dilemmas is too flat and proclamatory, as is the image of Ostrava's industrial environment; the heroes are thinking about one thing: the proper completion of the assigned task...

The holidays began and Pepík Janousek is playing with his friend Hadraba, whose nickname is Sun. Sun has to baby-sit his small brother in a pram and envies Pepík his nice adoptive parents because his own father beats him often. Pepík is happy - he will have soon the same surname Marek as his father and mother. Pepík is shocked when Sun tells him that Mrs Marková is pregnant. He falls from a height and ends up in hospital. Despite of all expressed love and care Pepík is afraid that the Mareks will no longer want him.
