An Arkansas community is rocked by the unsolved murder of two schoolchildren as this acclaimed crime drama returns for Season 3 after an extended hiatus. Academy Award winner Mahershala Ali ("Moonlight") stars as West Finger, Ark., police detective Wayne Hays, who remains haunted by the case more than three decades later. The story plays out in three timelines: the 1980 crime and subsequent investigation, new developments that arise in 1990, and 2015, as Hays reflects on the mystery. Stephen Dorff and Carmen Ejogo also star.
