Senator Ranse Stoddard returns to the city of Shinbone in the Wild West, to go to the funeral of his friend, Tom Doniphon. To a journalist, who's wondering what the senator is doing in Shinbone, he tells how his career started as "the man who shot Liberty Valance". As a lawyer he came to Shinbone to bring law and order to the west by means of law books. When the stagecoach is held up by outlaws, he is savagely beaten by Liberty Valance. He survives the attack and is nursed by his future wife, Hallie. Hallie is being wooed by a local rancher, Tom Doniphon. Ranse teaches the people of Shinbone to read and write, all the while trying to find a way of bringing Valance to justice. He finally takes up a gun and faces Valance in a menacing shootout.
