Sent back in time to feudal Japan, the Teenage Mutant Ninja Turtles immediately face a fight for their lives against…Yukichi and Jotaro! Mistaking the Turtles for the violent kappa terrorizing a nearby village, the long-eared samurai descend upon the Turtles with swords brandished. Can the TMNT convince Usagi’s allies to aid in their mission to stop Dr. WhereWhen from changing the future?

When the samurai rabbit embarks on a quest to save Japan and the deadly Jei blocks his path, a Turtle team-up may be the only chance for survival! These heroes have met before, but the samurai thinks something about the Turtles is different now, and that's bound to lead to some misunderstandings.
