The Turtles must infiltrate the Technodrome in order to save April. Meanwhile, Splinter faces off against Shredder after defeating Dogpound and Fishface. When he recognizes Karai as his long-lost daughter Miwa (whom Shredder had told that Splinter killed her mother), Splinter retreats in sorrow. Back at the Technodrome, the Turtles must get through Kraang Prime to get to April before Kraang Prime can abduct some human specimens.
