When Texas Mayor Ed Smith III was diagnosed with prostate cancer, he elected to forego conventional treatment in favor of a whole food, plant-based diet. The results were nothing short of miraculous: his cancer disappeared. He and his wife embarked on a mission to help their town and community adopt a healthier lifestyle based on plant foods. Their story is being told in THE MARSHALL PLAN. The documentary focuses on the transformation of one town into a healthier place when its residents adopted new eating strategies. The stories of Marshall’s residents are combined with interviews from expert doctors and researchers in the field of nutrition, and professional athletes.
