The war between the Great Ga'Hoole Tree owls and the Pure Ones leads to great strife and sets the stage for the quest for the legendary Ga'Hoole Tree.
Twin barn owl brothers, Soren and Kludd, are born in the Northern Woods.
Soren and Kludd are kidnapped by the Pure Ones and taken to St. Aegolius Academy for Orphaned Owls, a training ground for evil owls.
Soren escapes from St. Aegolius and begins his journey to find the legendary Great Ga'Hoole Tree to join the Guardians and stop the Pure Ones.
Soren meets the Guardians, a noble group of owls who protect the owl kingdoms, and starts his training with them.
Soren and the Guardians fight a decisive battle against the Pure Ones to save the owl kingdoms and the Great Ga'Hoole Tree.
Kludd, now known as Metal Beak, is defeated, ending his threat to the owl world.
The Guardians restore peace and order to the owl kingdoms, and the Great Ga'Hoole Tree stands strong once again.
