The Ninja Within chronicles the the afternoon of an ordinary kid who comes home after school to play their favorite video game. When they start playing everything transforms around them and they're suddenly in the digital world surrounded by a ninja clan!

In the first movement our hero has to collect themselves, coming to terms with what just happened. Once they've come to grips with the situation they join the ninja clan in training and then induction. Now that they've officially become a ninja it's time for a boss fight! At the end our ninja is transformed back to the real world... was it a dream? Or maybe it really did happen....

And while this show covers the literal story above, it also digs deeper and touches on the fact that we all have a ninja on the inside waiting to be summoned to do amazing things. Be it beat a boss in a video game, grade 400 papers after a long day of teaching, or run a marathon, there's nothing we can't do if we put our minds to it.
