Ten years ago, Judge Garth and his neighbor, Junius Antlow were on the best of terms, but one night, it all changed. Today, a rock slide has closed a pass that allowed Garth's herds to move from outlying pasture to the ranch. Garth is forced to seek out Junius to ask permission to cross his lands to bring the cattle in. Antlow is filled with hate and refuses, so Garth is forced to bring in Chinese laborers and a construction overseer to blow a tunnel to allow the cattle to pass. The Antlows use every tactic they can to block the tunnel until the price to to be paid is too high. One of Junius' tactics is to have Colton add explosives causing a cave-in that kills two workers and injures a third with The Virginian hurt during the rescue. The two are taken to Shiloh where they discover the worker is a young woman passing as a man, who falls in love with The Virginian as they recover. Betsy learns the ways of the Chinese from her as she learns about American life style.
