The movie we are viewing is Twelve Angry Men, directed by Sidney Lumet in 1957.

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 of murder soon becomes a mini-drama of each of the
juror's prejudices and preconceptions about the trial, the accused, and each other. Based on the play, all of the action takes place on the stage of the jury room.
