loose remake of “12 Angry Men”, “12” is set in contemporary Moscow where 12 very different men must unanimously decide the fate of a young Chechen accused of murdering his step-father, a Russian army officer. Consigned to a makeshift jury room in a school gymnasium, one by one each man takes center stage to confront, connect, and confess while the accused awaits a verdict and revisits his heartbreaking journey through war in flashbacks.
