Angela (Jennifer Carpenter, ‘Dexter’s sister’) and Scott form a tv-crew that are going to spend a night with the local fire department. It takes a long while before the first call, but the men are called for a medical call (which are most, the commander says) in the middle of the night. A woman in an appartment building went berzerk and soon several people are wounded. Assembling all inhabitents in the lobby below, it soon becomes clear that people outside do not want anyone to leave the building. Of course things go from bad to worse when the story takes a very predictable turn.
