After fulfilling the praying ceremony, the three oldest children of the alien Fogg Mother hunt for an ideal human in order to feed that person to their newly hatched siblings. They find such a person in Kana, the younger sister of environmentalist reporter Kouji Segawa as he was investigating pollution by the lake. Protecting Kana from the villains as they escape from them, Kouji is thrown over a cliff by the reptilian Agito and dies as Kana is taken by the insectoid Zu.

However, Kouji is then resurrected by the Earth Spirits to become Kamen Rider J, in order to fight the Fog Mother with the Earth Spirits' emissary Berry as his guide. With Fog Mother sensing Kouji's presence, Agito attempts to finish the job in his true form, only to be killed by J. Then Kouji enters the Fog Mother's domain and faces Zu as she assumes her true form. J manages to kill Zu as they both crash into the fortress which is Fog Mother.

After Zu dies, Kouji learns of Fog's intention of letting her new brood devour humanity, as Garai completes the ritual and sends Kana to the hatching chamber while manhandling Kouji. Berry intervenes to free Kana from Fog's spell before being struck down by Garai, as Kana is sent down to her death, while Fog Mother begins attacking a nearby city to prepare for her children's awakening. J fights Garai in his true form, Cobra Man, in a heated battle. After killing Garai, J is digested by Fog Mother as he attempts to save Kana.

However, absorbing the life energy around him, J kills Fog's newly born offspring and escapes Fog Mother's bowels and assumes Jumbo Formation. After ripping Kana out of Fog Mother, J battles the monster and kills her as she attempts to take him down with her. After escaping Fog Mother's destruction, Kouji takes Kana to a serene environment, with Berry watching from a distance.
