Based on Stephen King’s best-selling Bill Hodges Trilogy, which includes, "Mr. Mercedes", "Finders Keepers" and "End of Watch". Season 1: Two years ago, a psychopathic killer drove a stolen Mercedes into a crowd, killing 16. The recently-retired detective who headed the unsolved case suddenly begins receiving mysterious messages containing unreleased information and decides to start his own, unofficial investigation. Season 2: A year after his thwarted attempt to perpetrate a second mass murder in the community of Bridgton, Ohio, Brady Hartsfield remains hospitalized in a vegetative state. Retired Detective Bill Hodges has done his best to move on from his Brady obsession, teaming up with Holly Gibney to open Finders Keepers, a private investigative agency. But when unexplainable occurrences begin to affect hospital staff members attending to Brady, Hodges is nagged by the feeling that Brady is somehow responsible.
