When a student is found murdered by a sword and his Sikh classmate is charged, twelve jurors come together for the first day of testimony in what is to be a very controversial trial.

The trial continues as the jurors explore their own faults and fears: recovering alcoholic Johnnie gets close to Rose, while Elsie deals with severe medical issues.

Marcia Thomas reports a threat, Rose and Johnnie share an intimate moment and the trial moves forward when Duvinder is called as a witness.

The trial takes a turn when the defense calls a convincing new witness to the stand. Meanwhile, Johnnie continues his relationship with Rose, even after a warning from his counselor.

Jeremy buys into Mark Waters' latest scheme, Charles continues to help Elsie, Johnnie takes a thrashing and the barristers make their final arguments before submitting to the jury.

As the jurors manage their personal turmoil, they begin to methodically review the inconclusive evidence, revealing personal experiences and past trauma.
