Black Wedding (2021)

Original title: Crna svadba

After a horrible massacre in a village where twelve people lost their lives, the killer shoots himself in the head, but with a strange combination of circumstances, he still remains alive. Petar, a BIA operative, is trying to figure out what actually happened because the killer, before he shot himself, uttered the word "katabaza", the same one that his late son said before he committed suicide. The psychologist Natasha helps him in that, who, unlike Petra, rationalizes the whole case, and does not think that there is anything mysterious in it.
