Kamen Rider 1 is a 2016 film, part of the 45th anniversary of the Kamen Rider Series. It is also part of Toei Company's Super Hero Year project.
45 years ago, a man was subjected to the experiments of the secret organization Shocker and became a cyborg. Since that day, the man’s sole mission has been protecting humanity and justice from the threat of Shocker. His name is Takeshi Hongo, the first Kamen Rider.
Forty-five years since his transformation, he has returned to Japan once more to protect a girl who seems to be crucial to Shocker's plans to resurrect Ambassador Hell. Takeru Tenkuji, Kamen Rider Ghost, and Makoto Fukami, Kamen Rider Specter, join to help him. However, the years have not been kind to Hongo, whose cyborg body has become weaker. They must also contend with another evil organization claiming to be Shocker known as Nova Shocker.
In the wake of this new threat to the world, Takeshi Hongo transforms as his voice cries “Henshin!”
Will this be the final chapter in the story of Takeshi Hongo? Or will it be the prologue of a brand new legend?
For life, love and future.
