The film opens on Dino Earth fifteen years ago with a village elder telling the story of how Princess Freezia sealed away a pair of evil Bakuryuu with the Holy Sword, encasing them in ice. If the evil creatures are ever released from their prison, the world will end in a grip of fear "encased in white".

An elderly dog goes to a time machine, which he plans to use to drive to the future so he can meet with "someone" who gives him a kendama. However, the machine goes haywire and the dog is regressed back to his infant state, eventually found by a researcher cat.
