Premiering in the Frontier section at the Sundance Film Festival in 2002, John T. Caldwell’s experimental, ethnographic documentary explores the internal borders that extend well beyond the international line between Mexico and America, sharply dividing migrants in Orange and North San Diego Counties from the affluent suburbs that depend on their labor. In ravines and arroyos, migrant workers, including families, live in shanty enclaves in the shadow, literally in some cases, of the gated communities where they work. Working closely over several years, with Indigenous labor activists and Devora Gomez, Caldwell dissolves the line between filmmaker and subject by including forms of migrant self-representation that underscore the humanity systemically erased by design from the suburban consciousness.
