Serving as the true ending to Kamen Rider Decade and revealing the origins of Kamen Rider W, this movie is split into three parts. In "Kamen Rider Decade: Final Chapter", Tsukasa Kadoya fully embraces his title as the Destroyer of Worlds. In "Kamen Rider W: Begins Night", Shotaro and Philip recount the night on when it all began. Elements of both parts converge in the movie's final part, "Movie War 2010" as our heroes fight the forces of Super Shocker.
