“The Turtles take over what's left of Baxter Stockman's equipment, to help them track Shredder and the Technodrome and create the turtle Van. Shredder opens a portal to Dimension X in hopes to obtain new weapons. Instead, The Nutrinos - three teenage hot-rodders, and two of Krang's militant Stone Warriors, General Traag and one soldier, come through.” – IMDB
