Beijing is still afloat above the Earth, and The Shredder wants the Triceraton anti-gravity unit for his plans. But if he rips it out the city, and everyone within it, will plummet to the ground. The Turtles must work with Karai to stop his plans.
This episode provides examples of
- Catch a Falling Star: Karai does the falling, Leo does the rescuing
- Crazy-Prepared: Donatello packs gliders for all the Turtles, despite the fact that they get dropped out of the blimp is not part of the plan
- Enemy Mine: the turtles and Karai work together to prevent The Shredder from removing an anti gravity machine left behind by the Triceratons to prevent the city of Beijing from crashing down to Earth as well as saving the city in the process
- Floating Continent: Beijing, China, thanks to the Triceratons
- Never Say "Die": Surprisingly subverted in this one-off episode, substituting the normally used 'destroy' for 'kill' and 'dead'.
