Set against the sprawling, untamed landscapes of the American West, The Long Trail follows a mismatched group of pioneers and outcasts on a perilous wagon train journey to California. Among them are Perry, a bookish runaway with a broken moral compass; Nelly, a fierce, independent teen grappling with her traumatic past; and Samson, a grizzled mountain man haunted by the ghosts of his failures. Together, they must navigate not only treacherous terrain but their own demons, as they battle bandits, harsh elements, and the unyielding pressures of survival.
