When an ancient Japanese artifact is discovered in New York, the Teenage Mutant Ninja Turtles find themselves caught up in an epic adventure through time. It all begins when Splinter, the group's master and father figure, is transported to feudal Japan after the turtles attempt to save their friend April O'Neil, who is in danger due to her curiosity about the mysterious object.
The turtles—Leonardo, Donatello, Michelangelo, and Raphael—decide to follow their friend and rescue Splinter. Upon arriving in the samurai era, they find themselves in the midst of a conflict between a noble warrior and a tyrannical oppressor. The turtles must quickly adapt to the customs and culture of this time period while battling a gang of ninja warriors and other dangers threatening the balance of time.
With the help of unexpected allies, like a young samurai and a brave princess, the turtles embark on a mission to save both Splinter and the land they now call home for a time. As they face epic battles and thrilling challenges, the loyalty between brothers and the value of friendship are put to the test, leading the Turtles to discover what it truly means to be a hero in any era. With humor, action, and impressive fights, this adventure ensures that the turtles will always be ready for battle, no matter what time they find themselves in.
