Long Bright River is a Peacock limited series adapted from Liz Moore's acclaimed 2019 bestselling novel, developed for television by Moore herself alongside showrunner Nikki Toscano. Part police procedural and part intimate family drama, the eight-episode series pairs a tense murder mystery with an unflinching portrait of addiction and the bonds between sisters.

Amanda Seyfried stars as Mickey Fitzpatrick, a patrol officer working the streets of Philadelphia's Kensington neighborhood, an area at the epicenter of the opioid crisis. When a series of murders begins claiming victims on her beat — at the same time that her estranged sister, who struggles with addiction, goes missing — Mickey's professional investigation and her desperate personal search become impossible to separate.

Reviewers praised Seyfried's raw, deeply committed lead performance, which carries nearly every scene, as well as the show's compassionate handling of difficult subject matter. Atmospheric and character-driven, Long Bright River rises above conventional crime television by keeping its focus on the human cost of the crisis at its center rather than on procedure alone.
