The weak teenager Akira Fudo has been protected by his best friend Ryo Asuka since they were children. When Akira's parents die in an accident, the family Makimura brings him to live with them, and Akira falls in love for the gorgeous Miki Makimura. When the father of Ryo accidentally opens a gate to hell in Antarctica, demons are released, merging with humans to survive. Akira hosts Amon and becomes Devilman but keeping his humanity while Ryo hosts Satan. The hysteria and panic replaces reason and mankind initiates a war against the demons, but destroying also themselves.
The film was criticallly panned by movie reviewers and Devilman fans for its mostly bad acting, disjointed and confusing story and overuse of CGI. In an online poll, it was ranked the 3rd worst live action film adaptation of an anime or manga.
