An orphan grows up to become an Old West legend as the story of the Lone Ranger comes to the big screen in this western saga featuring Christopher Lloyd and Jason Robards. Orphaned as a young boy, John Reid struck up a lifelong friendship with a loyal Indian boy named Tonto. Years later, Reid has become a lawyer and returned to the west in order to ensure that vicious murderers such as the Cavendish gang are brought to justice. Having previously murdered Reid's parents, the Cavendish gang proves that they still rule this lawless land when they launch an ambush that leaves the lawyer serious wounded and his Texas Ranger brother dead. Nursed back to health by his old friend Tonto, Reid dons a mask and sets out to pursue justice anonymously atop his faithful horse Silver. His timing couldn't be better, either, because the Cavendish gang is about to carry out their most ambitious misdeed to date by kidnapping President Ulysses S. Grant (Robards). Upon learning that the president has been abducted by the most violent gang in the Wild West, the Lone Ranger sets out to settle an old score while rescuing the man who will steer the fate of a nation.
