Welcome to Ogden Marsh, Iowa: the friendliest place on earth. A picture perfect town where your neighbours are your friends and your friends are your neighbours..... Until they want to kill you. A mysterious toxin in the water supply turns everyone exposed to it into mindless killers and the authorities leave the uninfected to their certain doom in this terrifying reinvention of the George A. Romero horror classic. Sheriff David Dutten (Timothy Olyphant) and his pregnant wife, Judy (Radha Mitchell), find themselves trapped in the once-idyllic town they no longer recognise. On the run from infected neighbours, loved ones and friends, targeted by the ruthless military and terrified of getting sick, they are forced to band together with other survivors in a desperate struggle for survival.
