Undocumented immigrant Abril and her 2-year-old son Julian live on one side of a great wall in suburban San Diego. Her husband, Julian’s father Uriel, lives on the other side in Tijuana, Mexico. Each Sunday, Abril, Julian and Uriel join hundreds of splintered families making the trek to meet at the border wall, where American helicopters circle overhead and the only contact is the touch of fingertips through the metal slats. Through the Wall is the heartbreaking story of a family separated by the U.S.-Mexico border who spend time together the only way they legally can.
