A special episode for the Fourth of July: After reporting on tragedy after tragedy, a TV journalist struggling with anxiety discovers a cure in technology prescribed by her doctor – and quits her job to devote herself to using that technology to help America’s war veterans. She and the doctor team up to enhance that technology – doing some of the nation’s first hard-science experiments on blending virtual reality and biofeedback – and soon this simple solution begins to have far-reaching implications in the treatment of psychological disorders for veterans, first responders, and those suffering from PTSD in all walks of life.
