Saving General Yang

Northeast China, early Northern Song dynasty, AD 986. The Khitan army takes revenge for a past massacre, abducting General Yang Ye (Adam Cheng), leaving his wife and seven sons to rescue him, and falling into their deadly trap.
Led by the first son (Ekin Cheng), the seven - two of whom have never seen combat - set out with a small band of fighters to face an army of thousands, brave the treacherous Wolf Mountain, face the nemesis of their shared history, and find the way back alive - all to bring their father home.
