Forlorn River follows Ben, a horse-loving wanderer exiled by his father, as he struggles for respect in the wild sage-covered valleys of northern California. Estranged from family and tarnished by rumors, Ben's only solace comes from the open land-and a defiant rekindling of affection with Ina Blaine, his childhood sweetheart. Ben and Ina's bond deepens against a backdrop of frontier tensions, shady cattle deals, and personal reckonings as Ben fights not just for wild horses, but for a future where he is no longer an outcast.
