The Human Experiment lifts the veil on the shocking reality that thousands of untested chemicals are in our everyday products, our homes and inside of us. Simultaneously, the prevalence of many diseases continues to rise. From Oscar winner Sean Penn and Emmy winning journalists Dana Nachman and Don Hardy, The Human Experiment tells the personal stories of people who believe their lives have been affected by chemicals and takes viewers to the front lines as activists go head-to-head with the powerful and well-funded chemical industry. These activists bring to light a corrupt system that's been hidden from consumers... until now.
