April 1, 1957
Twelve very different jurors gather in a city courthouse to decide the fate of a teenager accused of killing his father. At first, the group believes that they should find the defendant guilty, but a thoughtful juror begins to cast doubt on the prisoner's guilt. One by one, the jurors examine the evidence again. They begin to realize that they were influenced by preconceived notions and that the defendant could be innocent. As a heated debate begins, the jurors' personal prejudices rise to the surface and endanger the course of justice.
