This movie takes place in an alternate universe (where its storyline could be considered a prequel to the events of the TV series). In 1999, an enormous meteor crashed onto Earth carrying extra-terrestrial creatures. In order to counter this new threat, ZECT was formed. Seven years later, in the year 2006, power struggles in ZECT have caused a new group, known as Neo-ZECT. With three groups in existence (Neo-ZECT, ZECT and the Worms), Tendou has decided to sell his power to either Neo-ZECT or ZECT, but his intentions are unclear. ZECT reveal a plan to save humanity, but unknown to other is a plot to destroy man kind.
The universe is not just one. Within the overlapping layers of the multiverse, there exists another Earth that looks exactly like Earth. In "MultiEarth ?0073", which has entered an era of cosmic coexistence, crimes involving the exploitation of energy-based lifeforms known as "Emorgy" are breaking out one after another. Reiji Doki, an investigator for the Galaxy Federal Police, is Gavan Infinity, the only person in the universe permitted to claim the title of "Space Sheriff Gavan". However, he is stationed in the backwater Archives Department. His true objective is to investigate Emorgy crimes across dimensions. Chasing these inter-dimensional threats, Reiji leaps through space-time, encountering the Gavans of various dimensions and joining forces to bring justice to the multiverse. "Jo-Chaku!" The Space Sheriffs Gavan transcend the boundaries of the universe to strike down evil!
The "rampage" of those with power, and the "resolve" of those without. The ultimate drama and psychic action is born here, where human evolution and conviction collide. A world where people began awakening to "psychic powers" one after another. Those who wielded their powers recklessly emerged, plunging the city into chaos. Amidst this turmoil, one police officer stood against them—Hikawa Makoto. He possesses no special powers, but he is an honest, clumsy man who believes in justice more straightforwardly than anyone.
College student and motorcycle enthusiast Takeshi Hongo is abducted by the evil organization Sustainable Happiness Organization with Computational Knowledge Embedded Remodeling, otherwise known as "Shocker", and converted into Batta Augment-01 as part of their plans for world domination. Before they can brainwash him to do their bidding, he escapes and uses his new enhanced abilities, renaming himself Kamen Rider, to wage a one-man war against Shocker.
