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.

Oldrich Danek, the scriptwriter for "Hic Sunt Leones", who made his debut as a director in 1960 with the officially irreproachable "Three Tons of Dust" ("Tri tuny prachu"), also turned to history - "The Nuremberg Campaign" ("Spanila jizda" - 1963) - to seek metaphors for the present. In 1967, Danek made his best film, "The Royal Blunder" ("Kralovsky omyl"), a fourteenth-century tale about the relativity of despotic power.
Historical material was by far the best medium for Frantisek Vlacil, who in 1967 completed his unique reconstruction of thirteenth-century Bohemia, "Marketa Lazarova", based on the novel by V. Vancura. Supported by the photography of B. Batka, he achieved an almost flawless recreation of a period that hovered between paganism and Christianity and filled it with authentic portraits of people from another civilization.
