Commander Spagnolo, accused of deliberately killing a young man from a disadvantaged neighborhood during an armed robbery, is about to stand trial. He asks Olivia to defend him, after losing trust in his attorney and firing him. Spagnolo swears to her that it was a case of self-defense and that the young man's death was an accident. Olivia agrees on one condition: he has to tell her the truth. This pact between them will be truly put to the test as Olivia begins to uncover the heavy family secret Spagnolo has been hiding, which may be linked to the young man's death. On the day of the trial, a terrifying shooting breaks out in the courtroom and Olivia finds herself face-to-face with the man who has been threatening her for weeks.
