Munje! is an urban comedy that takes place during a night in Belgrade. Mare, Pop and Gojko grew up together. Mare and Pop have always been musicians, while Gojko (who was harassed by them in school and has the nickname "Sissy") became a "guy in a suit," the boss of his own club and recording studio. Pop and Mare call on their old friend Gojko to help them release a record, but it doesn't go so smoothly. Gojko hasn't forgotten his school days and is now surrounded by bodyguards. On their way to the club, Mare and Pop meet a fake Santa Claus, a cool cop and, of course, girls.
