The proud Mexican tradition of corrido music—captured in the performances of Mexican band Los Tigres del Norte and the late Chalino Sanchez—provides both heartbeat and backbone to this rich examination of songs, drugs and dreams along the U.S./Mexico border. Al Otro Lado follows Magdiel, an aspiring corrido composer from the drug capital of Mexico, as he faces two difficult choices to better his life: to traffic drugs or to cross the border illegally into the United States.
