Where can I watch The Party in United States?

In the summer of 1991 the war broke out in Croatia. In a holiday house in Fruška Gora hills in Serbia, near the border with Croatia, a group of young people are having a birthday party. They try to have some fun and act like nothing is going on. The party is shattered by the war. They can hear the artillery, but something is also happening between them. Inevitably, some of the boys end up on the frontline and everyone of them is effected by the war that is starting to rage. "The Party" is about individual destinies of the characters trapped in isolated house in hills and surrounded by growing paranoia of the officially not yet declared war.
