Story Summary

Set between Season 2 (Revival of The Commandments) and Season 3 (Wrath of the Gods), the movie follows Meliodas and Hawk as they accidentally arrive in the mysterious Sky Palace, an island floating high above Britannia.

This ancient realm is home to the Celestial Clan, descendants of the Goddess Clan who guard a powerful relic: the Winged Sword. However, danger strikes when a demonic faction known as the Six Knights of Black attempts to steal the relic and unleash chaos across all realms.

A mistaken identity leads the Celestials to believe Meliodas is the reincarnation of an evil threat—until the demon assault forces them to work together.

The movie follows:

• Meliodas bonding with Solaad, a young Celestial warrior

• The Sins fighting side-by-side again in a large-scale battle

• The Six Knights of Black unleashing catastrophic power

• A race to prevent the rebirth of the terrifying Oceirus, a legendary winged monster

With stunning aerial battles, emotional teamwork, and a touch of comedy, Prisoners of the Sky delivers the classic Nanatsu no Taizai charm in a brand-new world.
