In Bahia, Brazil, generations of impoverished families live in palafitas, shacks built on stilts over the ocean bay. When the government threatens to reclaim the bay in the name of ecological restoration, hundreds of families are about to lose their homes. "Bay of All Saints" is a lyrical portrait of three single-mothers living in the water slums during this crisis. Their individual stories of poverty unfold through visits from Norato, their big-hearted refrigerator repairman, born and raised in the palafitas. As these women rise to fight for their future, they begin to see the bay in a whole new light.
