The America of the post-apocalyptic future is an irradiated wasteland - a vast, ultraviolent world where criminals control the mean city streets. Ultimate law enforcers like Dredd (Karl Urban) and his new partner, Anderson (Olivia Thrilby), are Judges - the only force battling for justice. Dispatched by the central authority, the Judges' target is Ma-Ma (Lena Headey), a ruthless boss bent on expanding her criminal empire through sales of Slo-Mo, a dangerous reality-altering drug. With Dredd calling the shots, the two judges declare full-scale war on crime in this unrelenting, brutal thrill ride.
