The story follows a young barn owl named Soren, who is kidnapped by owls of St. Aggie's,where owlets are brainwashed into becoming soldiers. He and his new friends escape to the island of Ga'Hoole, to assist its noble, wise owls who fight the army being created by the wicked rulers of St. Aggie's.

Guardians of Ga'Hoole is scheduled to hit theaters on July 30th 2010.
