Loosely based on the hybrid novel The Wrong Side of Goodbye from acclaimed author Michael Connelly, and a spinoff of the longest-running Prime Video Original, Bosch, the first season of Bosch: Legacy follows former LAPD detective Harry Bosch as he begins a new chapter as a private investigator. His first job calls him to the estate of ailing billionaire Whitney Vance, where Bosch is tasked with finding Vance’s only potential heir. Along the way, Bosch finds himself clashing with powerful figures who have a vested interest in the heir not being found. Researching the family tree, he uncovers shocking revelations that span generations, all while billions of dollars remain on the line. Without the badge and a preference for old-school tactics, Bosch finds an invaluable resource in Maurice “Mo” Bassi Stephen A. Chang, Captain Marvel), a tech-forward gadget whiz who also shares Bosch’s fondness for smooth jazz and commitment to justice.
