Manny Williams and his friends in the BAU are rocked. They return home from ordeals in North Carolina to find that Doctor Fredrick Argyle's body is missing from the Michigan cemetery where he was buried almost a year before. If the missing body isn't peculiar enough, Manny's wife, Chloe, receives an Argyle-like text from Las Vegas threatening the future of Manny's unborn child. Those circumstances send Manny and his team on a wild ride to Sin City-where the lights are bright and the murder bizarre-directly into the clutches of a killer who wants nothing more than to see Manny dead.
