Ballad of an Unsung Hero: Using rare historical footage, vintage musical recordings, and interviews with 88-year-old Pedro J. Gonzalez and his wife, this film chronicles Gonzalez’s long and colorful life, from his early days with Pancho Villa during the Mexican Revolution, to his career as a popular radio personality in Los Angeles in the 1930s, to the controversial court case that sent him to San Prison, a victim of the repressive forces operating against the Chicano/Mexicano community during that period.
