Part 1: After learning that the Kraang are planning an invasion, The Turtles engage in a difficult battle as they make a desperate assault on TCRI to shut down the Kraang's portal before it summons the Technodrome, and in order to save April whom the Kraang managed to capture with the help of Shredder.
