The narrative begins with a jarring revelation: during a routine medical exam, a cardiologist (played by Franziska Petri) informs her patient (Dejan Lilić) that their respective spouses are having an affair.

Rather than immediate confrontation, they choose to haunt the spaces of their spouses' betrayals—renting the same hotel rooms and retracing the steps of the illicit lovers.
