The juxtaposition of animals locked in cages in a zoo and people shackled by the confinement of the city has not lost its impact to this day. The amorous enchantment, passing and bonding of the two protagonists, a young conservationist and a paleontologist, takes place against a backdrop of subtly affected period realities. The debuting filmmakers, screenwriter Jaroslav Vanča and director Václav Křístek, have attempted to spice up the story with the character of a mysterious man who turns out to be the writer of the events just narrated.
