In a desolate, near-future America, a lone wanderer known only as the Last Son Sam Worthington traverses the brutal landscape, a man burdened by a mysterious past and driven by a singular, protective purpose. His solitary existence is shattered when he crosses paths with a desperate woman Heather Graham and her young son, who are fleeing a relentless and violent gang led by the ruthless Moses Thomas Jane. As this makeshift family seeks refuge, they are hunted by Moses and his brutal enforcers, including the volatile Bird Machine Gun Kelly, forcing the Last Son to confront the ghosts he tried to leave behind. Directed by Tim Sutton, this gritty action-drama paints a stark portrait of survival and redemption, where every choice is a matter of life and death. The film builds a tense, atmospheric world where loyalty is tested and violence simmers just beneath the surface, as a man who wanted no more war finds he must become a warrior once again to protect the last flicker of hope he has encountered.
