01PLOT

After spending three months in Northampton recuperating, the Turtles, Master Splinter, April O'Neil, and Casey Jones arrive in the lair surprised to see that there are no longer any Foot Ninja looking for them. They conclude that Shredder must have called off the search thinking that they were dead. Master Splinter states that being “dead” will give them a distinct advantage in their battle with Shredder this time.

By accessing city building records, Donatello and April develop a fair picture of the Foot HQ building, although there are some mysterious gaps in the information about several floors in the building. The pair is able to hack into the Foot's computers, offering an opening to a mutant offensive. Don establishes a communication link with April as she and Casey will stay in the lair and provide information about the building to the invading mutants. The guys pack all their weapons and Leonardo is designated to be the one to carry the Sword of Tengu, which they figure might come in handy in battling the Shredder.

Controlling the Battle Shell from afar, Donatello uses the remote to send the Battle Shell into the lowest level as a decoy while the Turtles enter the building stealthily through a sewage pipe. Hun reports to his master that the destroyed vehicle was empty and belonged to the Turtles. Shredder is stunned, but quickly realizes that Baxter Stockman had given him false evidence of his enemies' demise. Saki summons Stockman via a video com link, but the scientist ignores the order and continues working on a project. Shredder tells Hun to begin an immediate search for the Turtles. Meanwhile, April infects the building’s communication system with a computer virus and the Foot loose their ability to communicate electronically. The Turtles begin to make their way up through the building, floor by floor. At the same time, Hun begins the floor-by-floor search and destroy mission.

The Turtles soon find themselves in a huge hangar, filled with a variety of deadly looking weapons and vehicles. Splinter warns his students that he senses a presence in the room. Suddenly, the Sensei and Turtles are attacked by a group of invisible Foot Tech Ninja. At first the battle goes badly for Splinter and the boys, but the tide starts to turn when Raphael hops on one of the Foot vehicles and starts blasting away with its laser, which hits two of the Tech Ninjas and short circuits their suits, briefly disabling their invisibility capabilities. Don pulls a couple of tricks out of his hi-tech goodie bag, namely some electro-magnetic shurikens, which cause their enemies cloaking devices to short out. Only a few invisible Foot Tech Ninjas remain and the Turtles eventually reveal their presence by using fire extinguishers. Once Donatello can see his adversaries, he quickly disposes of them with more perfectly-thrown shurikens.

After winning another battle, the group moves up to the next level through a hole in the ceiling. They are shocked to see that they are in a Foot Genetics lab, like the one in the underground. The lab contains a number of large clear tanks that are filled with liquid and some strange looking creatures. As the guys study the tubes an alarm goes off and several tanks suddenly open, spilling out their contents. The Turtles stand gawking as three rather bizarre looking Mutant Shredder clones come walking menacingly towards them...

06TRIVIA

The Battle Shell is destroyed during this episode.
This marks the second appearance of a Foot Genetics lab. The first one was seen in "Notes from the Underground, Part 1", abandoned and destroyed by the mutants created there.
When Donny presses the code to unlock the lair, the beeping sounds are similar to part of the beginning of the theme song.
