Submission.

Three friends are hanging out on the roof in Sarajevo. Their hangout is interrupted by the Yugoslavian time traveler who explains them that they are in danger and need to use the time machine to go back to Yugoslavia and warn people that the future generations messed up. They travel back in time to find themselves not in Yugoslavia, but in Iran. Clash of the cultures is evident, and they are forced to hide their identity. But the more they discover the city, the more they realize it is scarily similar to their own.
