In the court, the sentencing of an 18-year-old boy accused of killing his father is underway, and the final trial also needs to consider the opinions of the twelve jury.
These twelve people each have their own careers and lives. Among them are clever advertisers, architects who speak up, justice and courageous office workers, new aristocrats who discriminate against common people, watchmakers who pursue the truth, and shrewd and calm people. Bankers, salesmen in a hurry. Everyone has their own way of thinking and speaking, but except for the architect played by Henry Fonda, everyone else dismissed the case and decided that the boy was the murderer before the discussion.
All the evidence shows that the boy is guilty, and everyone feels that there is no need for discussion. But the first voting result was that the boy was deemed guilty by 11 to 1. According to legal procedures, there must be a unanimous opinion, that is, the 12 to 0 voting result will be accepted by the court.
It was No. 8 who first stood up in favor of innocence. Because of No. 8's insistence and scientific speculation on the three key evidences, the atmosphere for innocence began to spread among the other eleven jurors. Voting on whether the boy is guilty has also begun to change dramatically: 11 to 1, 9 to 3, 8 to 4, 6 to 6, 3 to 9, and 1 to 11.
In the end, through the conflicts of different outlooks on life and the contest of different ways of thinking, all the jury members cast their sacred vote responsibly. Finally, all 12 jurors reached a consensus: not guilty!
