The future America 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 Thirlby), 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 and brutal, three-dimensional thrill ride.
