Long Bright River (2025) is a police procedural based on the eponymous novel by Liz Moore.

Mickey (Amanda Seyfried) is a Philadelphia police patrol officer working in a high-crime area.

When 3 women are found dead, and her ‘superiors’ decide these are suicides rather than homicides, Mickey begins to investigate the deaths.

We find out during the series that Mickey and her younger sister Kacey (Ashleigh Cummings) were raised in the kinship care of their grandfather (John Doman).

We also find out **spoiler alert** late in the series that Kacey’s now 8-year-old son was removed from her by the state when he was a baby. Mickey has been raising Thomas (Callum Vinson) as if he is her own child.
