The Seven Deadly Sins: Prisoners of the Sky (劇場版 七つの大罪 天空の囚われ人, 2018) is a Japanese anime fantasy film directed by Noriyuki Abe and Yasuto Nishikata — watch online on iFILM. Meliodas and Hawk are hunting for sky fish, a legendary ingredient, when they stumble onto a palace floating high above the clouds.

The people there are in the middle of a ceremony — one held every three thousand years to keep a monstrous beast sealed away. The Six Knights of Black, advance soldiers of the Demon Clan, shatter the seal before the ritual can finish. What follows is a full-scale assault on the sky kingdom, with Elizabeth and allies from the fairy and giant clans joining the fight. The film is based on Nakaba Suzuki's manga series from Kodansha's Weekly Shonen Magazine.

Unlike a lot of theatrical anime spinoffs that feel like extended TV episodes, this one gets a noticeably larger action budget and a self-contained arc that new viewers can follow. Stream The Seven Deadly Sins: Prisoners of the Sky (2018) online on iFILM.
