A group of children are investigating a chain of mysterious events during the seventies.

Sixteen-year-old students of a grammar school are supposed to write essays on "Love". The class best student Andrea (Jaroslava Schallerová) writes about a patriotic love to a country as she has no experience with a partner love. She has been living alone with her divorced pretty mother Eva (Milena Dvorská), a dentist, for many years. Recently, however, Eva met her former school-days love at a graduates' party, nowadays a famous hockey goalkeeper Brukner (Frantisek Velecký). Also his marriage fell apart; he leaves the national team and decides to leave Prague for his home town and to share flat with Eva. He takes with him his son Petr (Oldrich Kaiser), in Andrea's age, who gets his last chance to finish a grammar school in the town.

It is the 1920's. The good-looking hostess Věra demonstrates household robots to visitors of the Futurum exhibition. Young inventor Petr comes to her rescue when she tries to flee from two men wanting to take her away. Věra confesses that she has fled from home because her father, a factory owner, wanted to profitably marry her off. Petr is fascinated by the emancipated woman and shows her round his laboratory, where he plans to create a robot of his own - but one that would be far more advanced. Věra cuts herself on a broken test-tube and a drop of her blood gets in the solution. In the morning, they are taken aback to see Věra's double. This lucky chance has helped Petr create an artificial being, Miss Golem. She has a single motive for her actions: to take care of Věra and allow her to do only what is good for her.

In the thick woods at the edge of the Bohemian Forest, two border guards are keeping watch - rifleman Kucera (Rudolf Jelínek) and dog handler Stencl (Josef Hajducík), whose sluggishness and clumsiness have won him the nickname Simpleton. The official army dog, the bitch Líza, picks up the scent of an alien dog on the German side - Black Wolf. She bites through her leash and runs away. Soon afterwards, the border boundary was interrupted. The two soldiers are wounded in the gunfire that follows, but Stencl's shot also hits the target and the intruder - an attractive woman in a black jersey - is dead. The investigation reveals that this agent knew someone among the local residents. The locals are all called in to identify the body but nobody admits to knowing the woman.
