The year is 1927 and professional boxer Emmett Roane is losing his grip on reality. His career is faltering, memories of a lost love haunt him and the horrors of the Great War muddle his mind. Emmett's past is hobbling his future, and no amount of booze or knockout blows can ease his painful memories. Seeking solace in the place where he and his Anna had once been so happy, Emmett leaves Brooklyn for a few days alone in Newport at the gilded waterfront Hermann Hotel. During a fateful weekend as he tries to make peace with his ghosts, Emmett crosses paths with Maude Mable, a lively beauty with secrets of her own. But they soon learn the luxury hotel also hosts Luther Irvin, an opium-addicted mobster who is as violent as he is desperate. When Emmett and Maude discover Luther's hideous plan to wage war on a rival gang, the pair is thrust into a deadly match of wits and force. His back against the ropes, Emmett finds his quest for self-restoration has become a mission of survival-for him, Maude and everyone at the Hermann. Can Emmett Roane, a fighter who desperately seeks an elusive peace, halt the embodiment of evil while finding a way to heal his own heart and mind?
