When a magic scepter accidentally transports April back through time to 17th Century Japan, the boys take-off in hot pursuit, cowabungling their way out of the sewers right into Samurai-O-Rama! Now they must battle the evil Lord Norinaga to reclaim the magic scepter that will bring them back below the subways of New York City.

The turtles find out where the Ooze, the substance which made them mutate, came from. Unfortunately Shredder learns about it too, and uses it to enhance himself. So the turtles have to prove again who's the better ninja fighter.
