A 19-year-old man has just stood trial for the fatal stabbing of his father. “He doesn’t stand a chance,” mutters the guard as the 12 jurors are taken into a bleak jury room. It looks like an open-and-shut case—until one of the jurors begins opening the others’ eyes to the facts. Each juror reveals his own character as various testimonies are re-examined, the murder is re-enacted and a new murder threat is born before their eyes! Tempers get short, arguments grow heated, and the jurors become 12 angry men.
