A group of five teenagers break into their high school after hours hoping to throw a party. When they find themselves sitting idly in a dimly lit classroom with only a small boom-box and some red balloons, they realize their party is not a party at all, and begin to argue. The group's ringleader begins to alienate the odd one out, Sam, who was only included because he had access to the school's key. Ultimately, the ringleader calls the police on himself for amusement. The film ends on Sam who stands alone, illuminated by the lights of a police cruiser.
