Based on Michael Connelly's best-selling novel The Burning Room (2014) and the real arson case that inspired it, the seventh and final season of Prime Video's Bosch puts Detective Harry Bosch's famous motto center stage: "Everybody counts or nobody counts." When a ten-year-old girl dies in an arson fire, Detective Harry Bosch risks everything to bring her killer to justice despite opposition from powerful forces. The highly charged, politically sensitive case forces Bosch to face a grueling dilemma of how far he is willing to go to achieve justice.

After a medical physicist is executed and the deadly radioactive material he had with him goes missing, Detective Harry Bosch finds himself at the center of a complex murder case, a messy federal investigation, and catastrophic threat to Los Angeles -- the city he's pledged to serve and protect.

Fifteen months after bringing his mother's killer to justice, Bosch finds himself seeking the truth on two fronts. New evidence in an old case leaves everyone wondering whether Bosch planted evidence to convict the wrong guy. And a murder at a Hollywood pharmacy exposes a sophisticated opioid pill mill, sending Bosch down a dark and perilous path in pursuit of the killers.
