Sent forty years into the past by a spell of Chief Sitting Bull, General George Custer and the 7th Cavalry joined with Davy Crockett in a desperate struggle to defend the Alamo. Now it's March, 1836. Having survived the battle, Custer and Crockett must decide how to win independence for Texas. Opposing them are the Mexican Army under Antonio López de Santa Anna, and the Brazos Convention, dedicated to imposing a slave constitution. Determined to prevent the American Civil War, the journey of Custer and Crockett will take them from the Gulf of Mexico to the gold fields of California, with the future of a continent hanging in the balance.
