The families of twin sisters are "infiltrated" by a mysterious triplet, who was separated from them at birth by their adopted mother. Her deadly plan is to frame one of the twins for murdering the other’s husband, and then assume the identity of his widow by killing her too... but not if the framed sister has anything to say about it.
Follow the violent world of the Dutton family, who controls the largest contiguous ranch in the United States. Led by their patriarch John Dutton, the family defends their property against constant attack by land developers, an Indian reservation, and America’s first National Park.
