In 120 AD, Rome's Ninth Legion disappears without trace in Scotland and its standard, a golden eagle, is lost forever to the shame of Rome.
The commander of those soldiers also vanishes and 20 years later, his son, Marcus Aquila (Channing Tatum) accepts a posting in Romanoccupied Britain to learn the truth about his father''s demise.
The young soldier is badly injured protecting his men and he recuperates with his uncle (Donald Sutherland) and slave boy Esca (Jamie Bell). Once he has regained his strength, Aquila heads north in search of answers, accompanied by Esca, a member of the tribe of savages who slew the Ninth.
The Eagle hinges on the rapport between the leads and Tatum is impressive, bringing a brooding physicality and emotional vulnerability to his role. Bell meanwhile gets his moment to shine in a touching scene, when Esca defies the orders of Aquila and refuses to leave him to his untimely fate.
