Voice-over introduction
Leonardo : There comes time in the life of the ninja when he or she must choose between the path that others would have them follow and the true path of their heart. Karai was raised by the Shredder, taught ninjitsu by the Shredder and she serves the Shredder still. But there's something about Karai that's different. She's not like the Shredder and because of that, Karai is going to have to make a choice between serving the Shredder and serving own sense of honor. I only hope she makes the right choice.

Plot synopsis
The Shredder has somehow survived the last encounter with the turtles. (Most likely cloned by a colony of biocides) And has a plan for global domination utilizing nine Utrom exo-suit based foot mechs. Among the army of deadly ninja robots is a cyborg duplicate of master Splinter, which the Shredder sends out to hunt down and destroy the turtles. The turtles destroy the robotic imposter with the help of a rogue Triceraton named Zog. The turtles discover the remote control module and trace the signal. They soon discover that the shredder is back in control of the foot and is manufacturing more robots. The turtles plan to infiltrate and blow up the ship. They're soon discovered and surrounded by the Foot.

Quotes
