A 19-year-old man has just stood trial for the fatal stabbing of his father. It looks like an open-and-shut case—until one of the jurors begins opening the others' eyes to the facts. Each juror revealing his or her own character as the 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.
