Standing before them is a new hero of justice Great-Z, who announce that he's going to take Yabai Kamen and his cronies as villains for his upcoming TV show. In order to reclaim their popularity (and getting their second season Un-Canceled), the Dogengers must sneak in to this new show and save the Secret Society of Darkness from the clutches of Great-Z.
