Voice-over introduction
Karai: Honorable father, though you are imprison among the stars, I bring you news that will set free your soul. I, your humble daughter, Karai, discovered the lair of your most hated enemies and led a full Foot attack force against them. Utterly defeated, all they could was flee. Donatello and the rat we left destroyed at the bottom of the river. Michaelangelo tried to burrow his way into safety, but he could not dig deep enough to escape my wrath. And Raphael was blown to smithereens in the turtles' own battle shell. All that remains is Leonardo father and once I find him, then you will truly and forever be avenged.

Plot synopsis
At The Ancient One's urging, Leonardo returns to New York to find the lair in ruin and his family missing. Utilizing a focus and patience he rekindled in Japan, Leonardo is able to follow the clues, but most importantly, his instincts, to track down the rest of the family. After leaving them underneath Central Park to rest, Leonardo confront Karai, easily defeating her in combat and warns her never to attack them again.
