Eleven jurors are convinced that the defendant is guilty of murder. The twelfth has no doubt of his innocence. How can this one man steer the others toward the same conclusion? It's a case of seemingly overwhelming evidence against a teenager accused of killing his father.

A jury of white men is ready to pass judgment on a Puerto Rican teenager charged with murdering his father. However, one juror forces the others to consider whether the evidence--or the jurors' own prejudices--influences their deliberations. The story plays out in real time over ninety minutes in one sweltering room.
