In 1857 Utah, a local Mormon militia butchered over one hundred West-bound pioneer families in what came to be known as the Mountain Meadow Massacre. The mass murder haunts Mormon daughters Lavinia and Hettie as they grow from friends, to mothers, to sister-wives, over a span of 40 years. Tethered to their polygamous doctrine and to the men who killed in its name, TWO-HEADED reveals a unique bond between two women as they attempt to reconcile their faith and the truth of their relationship.
