Der berühmte Filmemacher Zack Snyder (300, Watchmen Die Wächter) präsentiert seinen ersten Animationsfilm ein Fantasy-Familienabenteuer nach Kathryn Laskys beliebten Romanen über mythische Eulenhelden: Der junge Soren ist fasziniert von den epischen Geschichten seines Vaters über die Wächter von GaHoole diese sagenhafte Truppe geflügelter Krieger zog einst in eine gewaltige Schlacht, um die Eulen gegen die bösen Reinsten zu verteidigen. Als Soren und sein Bruder Kludd aus dem Nest direkt in die Klauen der Reinsten fallen, wagt Soren die tollkühne Flucht und wird dabei von anderen tapferen Eulen unterstützt. Gemeinsam suchen sie den Großen Baum, wo die Wächter wohnen: Sie sind ihre letzte Hoffnung denn im Kampf gegen die Reinsten gibt es für das Reich der Eulen keine andere Rettung.
