Shows the human and environmental consequences of the newly constructed international border fence between San Diego and Tijuana. Along the way the film considers the reasons for the fence with local and global perspectives on its effectiveness. Migrants, deportees, minutemen, coyotes, environmentalists, writers and academics all lend their experience and perspective in terms of human rights, democracy, NAFTA, globalization and the destruction of the Tijuana estuary, the last standing unobstructed piece of estuarine wetland left on the California coast.
