Prime Video has officially locked in the return of one of its most iconic detectives—but this time, fans will see a younger, rawer version of Harry Bosch. The streaming service announced that Bosch: Start of Watch, a prequel series set in 1992 Los Angeles, will premiere on January 10, 2027. The eight-episode first season will explore how a 26-year-old rookie named Harry Bosch became the uncompromising investigator audiences have followed for over a decade.
Since his debut in the 2015 series Bosch, the character—portrayed with steely intensity by Titus Welliver—has been a cornerstone of modern crime television. His mantra, "Everybody counts, or nobody counts," became a defining ethos, and his gritty, morally driven pursuit of justice across L.A. redefined the police procedural. After seven seasons of the original show and a three-season run of Bosch: Legacy, which concluded last year, Welliver's version of Harry stepped away from the small screen. But the universe Michael Connelly created is far from done.
In the recent spin-off Ballard, Maggie Q took the lead as Renee Ballard, a detective who tackles cold cases with empathy and determination. Harry appeared occasionally as a retired mentor figure, but his absence left a void that fans felt deeply. Now, Bosch: Start of Watch promises to fill that gap by going back to the beginning—showing the formative experiences that shaped the detective we know.
The new series stars Cameron Monaghan (Shameless) as a 26-year-old Harry Bosch, fresh to the LAPD and navigating a city on the brink. Set against the backdrop of 1992 Los Angeles, the story unfolds amid racial tensions, rampant gang violence, and a police force struggling to maintain order. According to Prime Video, Harry finds himself pulled into a high-profile heist and a web of criminal corruption that will test his loyalty to the badge and ultimately forge his lifelong code: "Everybody counts, or nobody counts."
Behind the scenes, Tom Bernado and Brian Anthony serve as co-creators and executive producers, with Bernado also acting as showrunner. The cast includes Omari Hardwick (Power) as Eli Bridges, a veteran cop who becomes Harry's training officer, alongside Ariana Guerra (Rosa) and JD Pardo (Cory). The series is based on Michael Connelly's novels, ensuring the same authentic, layered storytelling that made the original a hit.
For fans who have followed Harry Bosch from his first case to his final bow, Start of Watch offers a fresh perspective on a beloved character. It's a chance to see the idealism and grit that defined his early years, before the weight of the job hardened him. The January 2027 premiere gives viewers plenty of time to revisit the original series—or catch up on Prime Video's recent chart-toppers—while they wait.
As the release date approaches, expect more details about the series, including trailers and behind-the-scenes looks. In the meantime, fans can also explore other Prime Video offerings, such as Chris Pratt's action thriller or Ben Stiller's heist comedy, to tide them over. Bosch: Start of Watch premieres Sunday, January 10, 2027, exclusively on Prime Video.
