A failure as a teacher and a familyman, Shinichi tries to escape everyday live by dressing up as the superhero "Zebraman". Although the TV series was canceled after only 6 episodes, this cannot stop him from acting out his escapist fantasy in a self made zebra-suit. He gets more then he could ever wish for when his black-and-white dressed alter-ego seems to be the only thing to stand between absolute (green) evil and a happy ending.

Zebra City 2025 – music echoing across what used to be Tokyo from Zebra Queen marks the start of Zebra Time, a 5 minute window twice a day when the city population is free to commit any crime and the Vengeful Zebra Mini-Skirt Police and masked Zebra Police can shoot civilians at will. Zebraman wakes in the street, unable to remember the last 15 years, or his superhero past. He must rely on a band Zebra Time survivors, a man who played him in a TV show version of Zebraman and a mysterious silent girl to battle this Zebra obsession that is splitting the city in to absolutes of black and white.
