Voice-over introduction
Leonardo : A wise man once said: I've got a bad feeling about this. And right now, I know how he feels. Believe it or not, that's my brother Donatello. And right now, he's sick. Really sick. He was scratched by one of Bishop's outbreak mutants, and now he has become a savage, mindless monster. Had it been any of us, we would have looked at Don to save the day. But even with Leatherhead's help, we're no closer to finding a cure. With no other options, we tracked down the one man who might have a cure: the man responsible for the outbreak in the first place: agent Bishop. Bishop agreed to cure Don, but for a price. Infiltrating Foot central? It's an impossible mission. But what can we do? Our brother is sick. And there's nothing we won't do to save him. Even if it means... making a deal with the devil.

Plot synopsis
The Turtles go to find the Heart of Tengu and give it to Bishop in return for Donatello's cure. Initially, Baxter Stockman refuses to work with Leatherhead to find a cure, stating that there is no cure. When Leatherhead falls into a rage and almost destroys Stockman, Bishop calms him, assuring him that they will find a cure - providing the Turtles get the Heart of Tengu. The Turtles find the Heart in the Temple of the Foot HQ, and a battle with Karai and her minions ensue. The Turtles, along with the help of Casey and April, manage to escape with the Heart.

Meanwhile, back in Area 51, Leatherhead successfully creates the cure and tests it on various subjects, much to Stockman's chagrin. Just as the Turtles return with the Heart, Bishop initiates a self-destruct sequence on Area 51. They manage to give the cure to Donatello, who is finally back to himself, but exhausted. The Turtles escape with Donatello - and assure him that he didn't cause them too much trouble. After Bishop cures the outbreak, he begins to work with the crystal. The Foot Mystics destroy the relic, morph to human-resembling beings, and set off to find the "True Shredder".
