Following his divorce, Albert (Ivan Franěk), an older man, begins a passionate relationship with a significantly younger woman named Kateřina (Ivona Baković). However, Kateřina is simultaneously in a bisexual relationship with another woman, Gábina (Zuzana Částková). The three form an open, polyamorous love triangle that revolves around casual sex, swinging, and shared independence. The dynamic shifts dramatically when Kateřina expresses a desire to have Albert's child—bringing in themes of surrogate motherhood, emotional baggage, and unresolved past traumas that fracture their agreement.
