The Last Son is a 2021 American Western directed by Tim Sutton in which Isaac LeMay, a ruthless outlaw cursed by a Cheyenne prophecy that one of his own children will kill him, hunts down and murders his offspring one by one — all fathered with prostitutes across the Great Plains. His last remaining son Cal, a violent bank robber, sets out to kill his father after Isaac attacks his mother Anna. The film carries a strong Oedipal undercurrent — most disturbingly in a scene where Cal rips the lingerie from his own mother's shoulders — while the incest angle reaches its full Greek tragedy conclusion when Isaac is ultimately killed not by Cal, but by his daughter Megan, whom he had dismissed as harmless.
