Covek is not the character’s name. It simply means “man”in Serbian. None of the character’s have names.

My theory is that the main character is stuck in the loop until he finally acknowledges the evil he had done, and accepts his punishment. He only escapes the loop when he acknowledged what he had done as a killer and refuses the chance to become a killer again.

Another fun fact: the plaza where most of the story takes place is actually at the very center of Belgrade, and the busiest area in the city. I was really surprised when I recognized it, since I did not know anything about the movie going in.
