For four years, Donatello was cruelly imprisoned by a mysterious figure claiming to be the new Shredder. His family believed him dead until the day that he reappeared at their door. Now that the turtles are reunited, they must find a way to help their traumatized brother heal, and to prevent this unknown villain from seizing power over the Foot.

When a life changing accident befalls the Hamato family, it's only the beginning of trouble. Taking advantage of their ordeal, Shredder has tasked Tiger Claw with implementing a terrifying plan that threatens not only the turtles, but the whole of Manhattan. Will they come to terms with what has happened and be able to pull together in time to stop their nemesis and save the city?
