The documentary by director Kelly Noonan Gores takes us on a scientific and spiritual journey, where we discover that our thoughts, beliefs, and emotions have a significant impact on our health and that we possess the ability to heal. The latest studies show that we are not at the mercy of unchangeable genes and should not blindly trust alarming predictions. Rather, we have more control over our health and our lives than we have been led to believe. This film provides viewers with a new understanding of the wondrous nature of the human body and the extraordinary healing powers within each of us. Heal not only offers insight into the minds of leading scientists and spiritual teachers but also follows three individuals in their healing process, where much is at stake. Healing can be extremely complex and deeply personal, but it can also happen spontaneously in an instant.
