As Lord Vringath Dregg's command ship begins laying siege to New York City, outnumbered by the Vreen, the Turtles fight off as many as they can before Leo and Sal Commander are captured and taken to Dregg's ship. The others are forced to retreat and find somewhere to hole up for the time being. During that time, Bishop blames Mona for Dregg's invasion, citing that he must have followed her here when they came looking for Newtralizer. As Raphael, Donnie, April, Karai, Mona Lisa, and Bishop avoid the Vreen swarming the city, they are shocked to find the Channel 6 building being made into a hive where the citizens of New York are being taken by the Vreen to be cocooned as Dregg's prisoners.
Soon after, Newtralizer arrives to finish them off, but in a strange twist, Michelangelo reappears, now sporting powers similar to Newtralizer, and still very much alive, but despite his aid, Donnie and Karai are captured as well by more Vreen, leaving April, Raph, Mikey, Mona, and Bishop to return to the lair to regroup and plan their next attack. On Dregg's ship, Newtralizer complains about destroying the whole planet, but Dregg intents to capture the human/Terran population and make them into living egg sacs for his Vreen army.
Back with the good guys, Bishop will have the Earth Protection Force send in a team to help deal with the Vreen and Dregg's command ship, while April, Mona, Raph, and Bishop attempt to provide a distraction with the Turtle Mech for Mikey to infiltrate and free the others. After the EPF forces are overpowered and forced to regroup, the Turtle Mech does its best to deal with Dregg's command ship before being destroyed, attempting to weaken it with pesticide and fire, which helps as further damage from within allows the EPF to take notice and resume their own attack from the outside to cause even more damage.
After Raphael, Mona, April, and Bishop get inside, Mikey frees Sal Commander, Leo, Donnie, and Karai, and after Raphael gives Dregg a good dose of electrocution, knocking him out cold after Mona sees he's vulnerable to it after zapping him with Rook's weapon, Mikey and Sal Commander end up in the power core of Dregg's ship, where when Newtralizer is about to take out Mikey for good, Sal Commander gets his vengeance for the wounds Newtralizer gave him by knocking him into the ship's power core, setting off a chain reaction that causes Newtralizer to overload the power core with his own electrical abilities, threatening to destroy the ship, and everyone on it. Mikey puts himself in harm's way with his powers to try and delay the inevitable to give everyone else time to abandon ship.
Realizing its fate, Dregg's ship takes flight in a vain attempt to escape, but after everyone else bails out and lands on a rooftop, they watch as Dregg's ship explodes, hopefully killing the alien warlord once and for all, and the Newtralizer as well. Mikey soon emerges completely unharmed and alive, and as everyone celebrates, Bishop uses the device meant for Newtralizer to remove Mikey's electrical powers, but rendering him stripped of his ninja gear and clothes as well, leaving him naked, save for his shell. The mission over, Mona and Sal Commander prepare to return to Salamandria to report to their general of what has transpired, but Mona requests that she be transferred to Earth to protect it from further threats. Understanding her reasons for staying, Sal Commander grants his Lieutenant her request, and after Raphael silences Bishop when he tries to counter this (by beheading him), Raphael suggests that Mona hook up with the Mighty Mutanimals and work with them. With that, Mona and Raphael share an embrace as Karai, April, and Raph's brothers look on proudly.
