At the Bar (2007)

A group of drug-influenced lumpen teenagers from the suburbs of the city descends into the center where they do not belong, where they are excluded. They adopted a brutal method to seize rights that were not granted to them. Unaware of what will happen to them, cheerful and well-to-do university students are helpless in the face of this gun-wielding mob that suddenly raids the bar where they are having fun.
