Walt(2015)

At 85 years old, organic raisin farmer and lifelong river advocate Walt Shubin is not slowing down. He has dedicated the last 65 years of his life to restoring California’s once-mighty San Joaquin River to the wild glory he remembers as a young boy. Driven by his passion for the river, and despite worn out knees and joints, he takes us on a journey to help us understand why this river is so important to all of us as well.
