Boundaries of Fidelity

Must a crisis and infidelity in a relationship or marriage lead to its breakdown? Can love survive intimate connections with other people? And is it possible to be a good parent outside a traditional family? A penetrating examination of a married couple's life, whose crisis led to an open relationship. The ensuing process triggered reflections on relationships within the extended family, which the director follows with extraordinary openness and intimacy, and ultimately the film becomes a meditation on how only breaking through the circle of fear and lies at the personal and intimate level can be the foundation of a healthy and open society.

Diana and Tomáš have been living together for several years. They have two young sons. But infidelity enters their relationship, bringing with it secrets, distrust, and lies. Yet in the crisis that emerges, they are able to acknowledge that their failures are mutual, which opens a new opportunity for communication on a different level and mutual understanding, exploring deeper motivations and stories from childhood and the wider family. In a certain euphoria from glimpsing a way out of the crisis, they decide to try an open relationship. Over time, they discover that distrust cannot be shed as easily as it seems. The film traces their efforts in meticulous detail and with emotional depth, following their attempts to navigate the situation and not betray their love while also considering the children, who are necessarily part of the entire situation. Beyond this, it also portrays the family background from which the protagonists themselves came, and thus raises questions about whether it is possible to live differently and avoid family traumas that surprisingly and unreflectively can be passed down across generations – even when a prominent psychologist is among the ancestors.
