The "Plan DE San Diego" was hatched in the Texas town of that name during the Mexican Revolution by some Mexican Americans who hoped the plan would incite a rebellion to both help free African Americans living in the Southwest and to seed violence and enough mayhem to bring about the return to Mexico of its former lands. Professor Hernandez brings the turmoil of this early 20th Century period back to life as he details the way this plan's insurrection was thwarted and the cast of colorful characters involved in the chaos taking place on both sides of the border.
