After learning from Donatello’s online friend April that TCRI is not all that it seems, the Ninja Turtles find themselves going against Baxter Stockman’s plan to bring the vile Kraang to Earth. To do this, they must fight Stockman’s mutants, evade Splinter from discovering what they are doing, evade the government agent Bishop as he performs his own investigation on the company, and gain the aid of April’s father, Kirby, who also works at TCRI.
