After the Civil War, Colonel Lambeth returns to his country home in Georgia and is reunited with his daughter Terrill. Broke and with no immediate prospects, Lambeth and Terrill decide to sell their property and go West together to re-start their lives. Accompanied by their former slaves, Jonah and Mauree, Lambeth and Terrill start a caravan for Texas. After she is harassed severely by two lecherous gamblers in San Antonio, Terrill dons male clothing, while her father buys a herd of cattle with their savings. At the same time, Pecos Smith, a rowdy but honest cowboy working outside San Antonio, learns that fellow cowpunchers Sam and Breen Sawtell have been spreading rumors that he is a cattle rustler. Sure that the Sawtells are gossiping in an attempt to cover their own guilt, Pecos rides into San Antonio and confronts the brothers in a cantina.
