The narrative of Betrayal begins in a clinical, almost sterile environment. A male doctor (played by Dejan Lilić) attends a routine medical check-up conducted by a female cardiologist (Franziska Petri). The professional boundary is abruptly shattered when the doctor calmly informs her patient that their respective spouses are having an affair with each other.

"Betrayal" received generally positive reviews from critics, with many praising the film's gripping storyline and strong performances. The movie was also a commercial success, grossing over $1 million at the box office.
