Former mixed martial arts competitor Emily Fisher found her way into the octagon, in part, because of her husband Spencer Fisher, a popular UFC fighter. After his crushing defeat to Hermes Franca, in 2007, Spencer changed in ways Emily couldn't understand. Five years later an abnormal brain scan showed lesions on Spencer's brain, bringing his career in the UFC to an abrupt end. Emily Fisher shares her story of faith, love and the new fight the couple shares following the impact of brain injury.
