After exacting vengeance on his mother's rapist, a deeply troubled Native American named Wolf finds himself fleeing from the law, haunted by the memory of his mother's tragic death due to her brutal injuries. Six months later, he crosses paths with a drifter called Cash as they travel northward toward his sister's property, where he plans to fulfill his mother’s last wish by spreading her ashes. However, the law, hot on his trail, poses a significant threat to his journey.
While making their way through the desert, Wolf and Cash encounter a bloodied young boy pleading for assistance. Upon following the boy, they stumble upon a horrifying scene where a young woman is being assaulted by a white male. In a moment fueled by rage and compassion, Robert Wolf intervenes, knocking out the rapist and rushing to help the woman, who reveals the extent of her horrific injuries, with half of her face brutally beaten.
Panicked but determined, Cash rushes to locate a nearby police station, carrying the woman and child as he races through the underbrush. When they arrive, a police officer catches sight of them, quickly summoning help. However, as he turns to gather more details, Wolf and Cash make a split-second decision to escape. They freeze when the officer draws his weapon, but after understanding the dire circumstances they faced, he starts to comprehend the gravity of their actions.
Much to their surprise, upon learning that Wolf is the son of Chief Numay Wolf, the officer lets them go, urging them to flee before backup can arrive and alerting the authorities to the location of the rapist. After this heart-stopping incident, they escape deeper into the mountains to find shelter for the night.
As they settle beneath the stars, Cash asks Wolf about their narrow escape, prompting Wolf to share the haunting truth of his mother's violent past and his own path of vengeance. He explains how the justice system had failed him and his family, releasing the man who had committed the crime against his mother. This moment of vulnerability cements their bond, with Cash expressing his loyalty and enthusiasm to accompany Wolf on this significant journey.
Eventually, they arrive at a secluded sanctuary where Wolf reconnects with his sister, Eva, and brother-in-law, Irish. They also meet his godson, who carries Wolf’s name. In a moment of shared sorrow, Wolf confesses to Eva that he wouldn’t go back and change his actions regarding the murder, igniting a poignant discussion about their mother's legacy.
As they gather strength for the next leg of their journey, Irish offers to assist them, but warns that it’s too treacherous to continue riding on motorcycles in the frigid temperatures. Meanwhile, unbeknownst to them, they are being tracked. Upon returning home, Irish finds Eva distressed along with Agent Williams and Agent Schaeffer, who threaten to dismantle their family if they don't reveal Wolf's whereabouts.
With Wolf and Cash ascending higher into the mountains to perform the final ceremony for his mother, Irish is forced to lead the agents toward them while attempting to mislead them. Yet, the agents are sharp and take note of any clues pointing in the right direction.
In a final, desperate moment, as Irish catches sight of Wolf, he screams for him to run, but Agent Williams swiftly incapacitates him. The situation spirals as Agent Williams orders Agent Schaeffer to shoot Wolf, who in that instant knows he cannot remain free.
A heartwrenching chase ensues, leading to Wolf being shot in the back by Agent Schaeffer. As he lands on the ground, he realizes the depth of his despair. In an act of defiance and control, he takes a sharpened antler from his pocket and inflicts a fatal wound upon himself, choosing to go out on his own terms.
In a deeply emotional finale, Cash reaches Wolf, desperately urging him to hold on, but ultimately, Wolf passes away in his arms. Cash, witnessing his friend find solace, is left with a haunting image; the last scene shows them riding down the highway into the sunset, a bittersweet end to a harrowing journey defined by love, loss, and the search for peace.
