Plot: When oil is discovered in 1920s Oklahoma under Osage Nation land, the Osage people are murdered one by one - until the FBI steps in to unravel the mystery.
Alternative Plot: Based on David Grann's broadly lauded best-selling book, "Killers of the Flower Moon" is set in 1920s Oklahoma and depicts the serial murder of members of the oil-wealthy Osage Nation, a string of brutal crimes that came to be known as the Reign of Terror.
