Hieronymus "Harry" Bosch has retired from the LAPD and works as a private investigator. Defense attorney Honey "Money" Chandler has him work on some cases for her. His daughter, Maddie, navigates her first days as a patrol officer with the LAPD, working from Hollywood Station, where her father used to be assigned. Bosch investigates businessman Carl Rogers, who previously hired a hitman to kill Chandler. Billionaire businessman Whitney Vance asks Bosch to discreetly investigate a private matter.

Season 2 begins where season 1 left off, with the kidnapping of Maddie Bosch. Bosch and Honey "Money" Chandler work together to catch a killer, while dodging the suspicions of the FBI as suspects in a case from season 1: the killing of Carl Rogers. Maddie, following the kidnapping, struggles to find her place in her job.

Honey "Money" Chandler campaigns to become the Los Angeles District Attorney (DA) while Bosch investigates the disappearance of the entire Gallagher family and is implicated as a conspirator in the murder of Maddie's kidnapper, Kurt Dockweiler. Chandler is successfully elected DA. Bosch is cleared of involvement in the murder of Dockweiler and solves the Gallagher murders but the culprit flees to Mexico. Bosch investigates the murder of his colleague Jimmy Robertson and links it to a drug cartel, while Chandler deals with powerful political opponents. Maddie investigates a group of robbers. The finale has Bosch meet Detective Renee Ballard while investigating a cold case, and working with her to solve it.

Guest appearances are made by members of the Bosch cast, including Gregory Scott Cummins as Crate, Troy Evans as Barrel, Jamie Hector as Detective Jerry Edgar, DaJuan Johnson as Detective Rondell Pierce, Jacqueline Obradors as Detective Christina Vega, Cynthia McWilliams as Detective Joan Bennett, Alan Rosenberg as Dr. William Golliher, Scott Klace as Sgt.

In the last episode of season 2, late actor Lance Reddick appeared a final time as Ret. Chief. Irvin Irving following his death, while Chris Browning appeared again as Preston Borders, a criminal arrested by Bosch during his time as a detective. In the third-season premiere, Jamie McShane returned as Francis "Frank" Sheehan, a former detective fired after being exposed for police brutality. Later in the season, Juliet Landau returned as Rita Tedesco, Preston Borders' wife, while Verona Blue returned as Shaz, a bartender acquainted with Jimmy Robertson. Celestino Cornielle also returned as DEA Agent Charlie Hovan.

Welliver's younger son Quinn portrays Bosch as a child in Bosch; in Bosch: Legacy his elder son, Eamonn, portrays Bosch, now a young LAPD officer.

After the conclusion of Bosch, producers began discussing a new series that would feature Harry after his retirement from the LAPD, as happens in the later Bosch novels. Welliver admits that it is essentially Bosch season 8, but the focus is different: Harry is no longer a cop, and the main characters are Bosch, Maddie, and Chandler.

In April 2026, Titus Welliver stated that discussions were ongoing regarding a potential fourth season of Bosch: Legacy. He noted that while conversations had taken place between himself, Michael Connelly, and producer Henrik Bastin, no official renewal or greenlight had been issued.
