Sympathetically modern for its time - it was 1937 - is the approach of a young factory director in the middle of a growing Bata-style town in the picturesque foothills of the majestic Tatra Mountains. But make no mistake, the protagonist is his wife Helena (Eliška Křenková). However, the determined gaze of the aspiring doctor, who is about to give birth soon, into her dream family future is suddenly overshadowed by the discovery of a dead body of a newborn baby in the courtyard of the pulsating factory. Helen's innate empathy, amplified by another condition, is not satisfied with a conspicuously quick solution to the mystery. A gripping detective drama with a progressive and deeply human take on a controversial subject not only just before the unsuspected war but decades later.
