What the Series Is About
I Will Find You follows David Burroughs, a former law professor who has spent five years in prison after being wrongly convicted of murdering his three-year-old son, Matthew. His world is upended when his former sister-in-law, Rachel Mills, shows him a photograph suggesting Matthew may still be alive. That single image sends David on a desperate mission, forcing him to break out of prison and team up with a small circle of allies to uncover the truth. The story is based on Harlan Coben’s 2023 novel of the same name, and Coben himself serves as an executive producer on the adaptation, working alongside showrunner Robert Hull. The series was filmed primarily in Kingston and Toronto, Ontario, with the Kingston Penitentiary standing in as the fictional Briggs Penitentiary where much of the early action unfolds.

Why the Cast Works So Well Together
Much of the series’ tension comes from how believable the relationships feel, and that is largely a credit to the ensemble’s chemistry. Showrunner Robert Hull has spoken about how fortunate the production was to assemble this particular group of actors, noting that their rapport made the demanding shoot easier to navigate day by day. Lower’s involvement was especially notable given her packed schedule filming Severance at the same time, while Worthington’s grounded performance anchors the more far-fetched twists in a way that keeps the emotional stakes believable throughout.
Harlan Coben has also praised the ensemble, describing it as a dream cast capable of carrying a story that shifts between heartbreak, suspense, and hope. That balance is central to the show’s appeal, since Coben has said he wanted the series to explore darkness without losing sight of optimism.
How Many Episodes of I Will Find You on Netflix
I Will Find You consists of eight episodes, all released at once on Netflix as a complete limited series rather than a weekly rollout. Episode runtimes vary, with the premiere clocking in around 47 minutes and later chapters running closer to 35 to 45 minutes each. Because the series was designed as a self-contained miniseries rather than an ongoing show, all eight episodes tell one continuous story that reaches a definitive conclusion, closing out the mystery introduced in the very first scene.
What Happens in I Will Find You
The series opens with David serving a life sentence for a crime he insists he did not commit. Everything changes when Rachel shows him a photograph taken at an amusement park that appears to show Matthew, now several years older, alive and well. Convinced the boy in the photo is his son, David escapes from prison with help from insiders at the facility and begins working with Rachel to retrace the events surrounding Matthew’s disappearance. Their investigation pulls in a mix of dangerous figures, including a Boston mob boss with a personal vendetta and a wealthy family with long-buried secrets. Along the way, David and Rachel uncover lies from witnesses at his original trial, question the loyalty of people closest to David, and slowly piece together a conspiracy far more complicated than either of them expected. The season builds toward a high-stakes confrontation that finally reveals who took Matthew and why.
I Will Find You Ending Explained
The final episodes reveal that Hayden Payne, the man David and Rachel trusted most, is the one responsible for Matthew’s disappearance. Hayden had donated genetic material to a fertility clinic years earlier, believing Rachel was the intended recipient, when in fact it was Cheryl who used it, unaware she was already pregnant with David’s biological child. Believing Matthew was secretly his own son, Hayden killed a terminally ill boy from an orphanage connected to his family and used the child’s body in place of Matthew’s, manipulating DNA evidence to support the deception. He then raised the real Matthew under a different name for five years. When a detective from overseas begins connecting the orphan’s death to the Payne family, Hayden kills him to protect his secret, and later turns on his own mother after learning she lied to him about the paternity results. The series closes with a violent standoff at the Payne estate, where David is shot during a rescue attempt but survives, while Hayden is ultimately stopped by Agent Greer. In the aftermath, David reunites with Matthew, and while he and Cheryl do not get back together romantically, both move forward with newly rebuilt lives, and David’s story is later told in a book written by Rachel.
