Estranged from his family and forced to live in a grotty tower block on a crumbling estate, struggling artist Mark (Lee Ross) is having a bad day.
His alarm doesn’t go off. The power is out. The milk’s gone off. There’s no water. He’s got to be in court for a custody hearing and someone has glued shut his door, sealing him in his flat. He can’t get a signal on his mobile. Then his neighbours knock a hole in his wall looking for a means of escape as sinister, military figures in HAZMAT suits start rounding up the residents of the estate, dragging them to a makeshift treatment tent outside while a voice on the intercom assures them there’s no cause for alarm.
With paranoia and mistrust mounting and snipers picking off escapees, rioting breaks out and the army starts gassing the other tower blocks on the estate. If Mark and his neighbours are going to survive, they’re going to have set aside their differences and work together.
