12 Angry Men is a movie with a simple premise, but the ending of its conflict and themes are incredibly complicated. Based on Reginald Roses 1954 teleplay (not a book), 12 Angry Men shows the deliberations of a jury on a murder case in which a young boy is accused of killing his father and facing the death penalty. At first, the jury is nearly unanimous in finding the young man guilty, but the deliberations continue when Juror 8 (Henry Fonda) dissents. Juror 8 single-handedly manages to convince the other jurors that the case has room for reasonable doubt, eventually leading to a 12-0 not guilty verdict.
