Soren, a young barn owl, is kidnapped by owls of St. Aggie's, ostensibly an orphanage, 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. The film is based on the first three books in the series.
This movie contains 13 potentially triggering events.
Kludd is abused by the Pure Ones, being kidnapped and then trained as a soldier, but he voluntarily becomes one of them. He kidnaps his sister and attacks his brother.
(Spoilers) Kludd falls into flames. At the end, however, it is hinted that he might have survived. Soren reacts to the fall as though his brother died.
There's a 'blind snake' and she's polite and friendly, however, she looks like just a normal snake, which may be frightening if you don't like how snakes look.
Grimble is dropped by Nyra, but he'd already died or fallen unconscious before she dropped him. Kludd falls into the forest fire, but near the end of the movie it is shown that he survives.
