By 2025, fifteen years after the events of ''Zebraman'', Tokyo has renamed itself Zebra City, and has instituted a "Zebra Time" starting at 5:00 AM/PM for 5 minutes (in which all crime is legal) the government allows the Zebra Police to attack any and all presumed criminals. One Zebra Time results in the attempted murder of Shinichi Ichikawa, also known as Zebraman. Surviving the attack but having lost his memories, he must team up with television's fake Zebraman and a young protégé to save a mysterious little girl from Zebra Queen and her Zebra Police, and then the world from Zebra Queen's ultimate plan to use the strange aliens from 2010 to bring Zebra Time to the whole world.
