Highly decorated Navy SEAL Marcus Capone returns from Afghanistan and attempts to readjust to civilian life. But years of unprecedented warfare have left Marcus with treatment-defiant PTSD, traumatic brain injuries, and severe depression beyond what current government treatment options can effectively address. Fearing for Marcus' life, his wife, Amber, finds hope in a groundbreaking therapy combining two powerful psychedelics unapproved for use in the U.S., but with seemingly limitless applications. Inspired by Marcus' remarkable recovery but still confronted with the alarming rate of veteran suicide in their community, Marcus and Amber embark on a new mission: providing access to this lifeline. Alongside intimate interviews, captivating animation, and first-of-its-kind research at Stanford's Brain Stimulation Lab, In Waves and War, from Jon Shenk and Bonni Cohen (Athlete A, An Inconvenient Sequel: Truth to Power), is the emotional, inspiring odyssey of three American heroes as they overcome the after effects of war and rediscover their humanity.
