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.
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.
