Based on Michael Connelly’s internationally best-selling Harry Bosch book series with nearly 50 million copies sold, Bosch follows relentless LAPD homicide detective Harry Bosch as he pursues the killer of a 13-year-old boy while standing trial in federal court on accusations that he murdered a suspected killer in cold blood. Primarily based on elements from Connelly’s books City of Bones (2002), The Concrete Blonde (1994) and Echo Park (2006), Bosch’s investigation takes on a life and death urgency when a killer who has confessed to the boy’s murder escapes custody and begins a murderous rampage across Los Angeles. He and the killer are locked in a cat and mouse game, with the killer taunting Bosch as the investigation turns deeply personal. The case unearths Bosch’s buried past as well as entangling his ex-wife and 14-year-old daughter. The season takes the viewer through back streets and neighborhoods of Los Angeles rarely seen on-screen.
