Inspired by true events, ''Clash'' tells the story of Richard and Raymond, two teenage brothers on opposite sides of a gang war. Complications arise at a deadly midnight ''engkwentro'' (clash), when the head of Raymond's gang gives him the task of killing his older brother. All this happens while the City Death Squad lurks the streets, a real-life vigilante group allegedly backed by the omnipresent Mayor Danilo Dularte Suarez and responsible for many unsolved murders of teen gangsters. Today, they are hunting down Richard; will they take down Raymond, too?
