The defense and the prosecution have rested and the jury is filing into the jury room to decide if a young Spanish-American is guilty or innocent of murdering his father. What begins as an open and shut case soon becomes a mini-drama of each of the jurors' prejudices and preconceptions about the trial, the accused, and each other.

Sidney Lumet's feature debut is a superbly written, dramatically effective courtroom thriller that rightfully stands as a modern classic.
