Arizona, 1859. A hardened frontier doctor (Guy Pearce, The Brutalist) is hired to escort a determined woman and former slave (DeWanda Wise, Jurassic World: Dominion) on a four-day ride across the lawless West. Her mission: reach her daughter before a mysterious force consumes her completely. What begins as a simple escort turns deadly, as strange encounters, unexplained phenomena, and violent pursuers close in. Also starring Bill Pullman (Independence Day).
