Under the command of Flavius Aquila in A.D. 120, Rome's Ninth Legion marches north carrying its revered eagle emblem and vanishing into the mists. Rumors of the legion's golden eagle appearing in a tribal temple reach Marcus Aquila (Channing Tatum), Flavius' son, 20 years later. Accompanied by his slave (Jamie Bell), Marcus makes a dangerous journey to Scotland to retrieve the hallowed eagle and, in doing so, to restore his father's tarnished honor.
