Released to commemorate Kamen Rider 555's 20th anniversary, the film takes place after the ending of the TV series. Masato Kusaka and Mari Sonoda are fighting a new iteration of Smart Brain led by Kitazaki, who begins an operation to exterminate all Orphnochs, with Takumi Inui seemingly working with them for unknown reasons since his disappearance.

Genji and his victorious G.P.S. alliance find themselves facing down a new challenge by the students of Hosen Academy, feared by everyone as 'The Army of Killers.' The two schools, in fact, have a history of bad blood between them. And the simmering embers of hatred are about to flare up again, burning away any last remnants of the truce they had so rigorously observed until now.
