Patrimonio takes place in Todos Santos, a community of 6,000 on the Pacific Coast of Baja California Sur, Mexico. The film’s narrative arc tracks the town’s rising resistance to an multi national mega development that plans to build 5,000 houses in this vulnerable desert town. The development, called Tres Santos, is billed as ‘mindful’ and ‘holistic’ but threatens the dwindling water supply and the local beaches. We witness the town’s burgeoning awareness and activism through the eyes of Rosario Salvatierra, whose family has fished these hard waters for four generations, and John Moreno, a surfer, lawyer and environmental activist who takes on a life-altering cause.
