Leatherneck pops open another can of soda, climbs back inside the club and tells the other Joes that they now have to find a way back to Earth.

Dr. Mullaney meets Serpentor and the Cobra Emperor orders the doctor to begin outfitting Cobra planes with the nitrogen engine. After having his protests cut short, Dr. Mullaney angrily mutters, “Oh, you’ll get results!”

In order to help his friends return to Earth, Mainframe explains that Dr. Mullaney’s formula will be forwarded to them so that they can use the air inside the club to fuel the rockets.
“Excuse me if I sound like a total lamebrain - “ Leatherneck says.
“You’re excused, lamebrain,” Wet-Suit inserts.
“But ain’t Dr. Mullaney’s formula sorta dangerous?” asks Leatherneck.
General Hawk explains that it is extremely dangerous and Mainframe adds that unless the calculations are correct for the rockets, the club could explode.

While Leatherneck and Wet-Suit turn to one another and prepare to go back outside, Dr. Mullaney, who is under the watchful eye of Serpentor and two armed Cobra Vipers, converts the engines on ten Cobra Firebats.

As the Joes work on converting the club's engines, Wet-Suit chides Leatherneck for calling a “nut” a “bolt” and then pokes fun at the Marines. However, when they are back inside, Leatherneck simply replies, “Ha, ha. That’s about as funny as a screendoor on a submarine.”

Dial-Tone activates the engine, one of the club’s rockets fires up and the club begins to rocket back toward Earth. After Mainframe spots the club on radar, General Hawk orders Slipstream’s squadron to protect the club from Cobra. While rolling down the runway and taking off into the air, Slipstream yells, “Yo Joe!”

As several Conquest X-30s follow Slipstream, Serpentor watches the club’s descent toward Earth and orders the nitrogen engine planes to take off immediately and intercept the club. And one of the Firebat pilots tells Dr. Mullaney to climb inside his Firebat in case something goes wrong with his engine.

The club continues to fall back to Earth and Madeline grabs Leatherneck before shouting, “My hero!” But Leatherneck breaks free and yells, “Which way to the airlock, please?!”

The Conquest X-30x arrive and intercept the Cobra Firebats, and Wet-Suit crosses his arms and grimly notes that his teammates have a fight on their hands. Firebats fly in behind the Conquest X-30s, which peel away to avoid Cobra’s attack.

Slipstream glides in behind three of the Firebats, closes one eye and prepares to take a shot, however, the plane explodes before he pulls the trigger.

Two more Firebats angle toward Slipstream, who shouts that he is going to like this battle, but while they are firing, the Cobra jets explode.

After Dr. Mullaney suggests to the AVAC that they land soon before his own Firebat explodes, Slipstream yells, “Best fireworks display I’ve seen since the Fourth of July.”

After the last Firebat and the Conquest X-30s land, the Joes surround the Cobra plane. The canopy to the enemy aircraft slides open and Dr. Mullaney asks for the Joes to hold their fire. Slipstream steps forward to greet the doctor and asks how he destroyed the Firebats. “In his impatience to get my secret, Serpentor didn’t ask if it worked,” replies Dr. Mullaney. And while all of the Joes laugh, the Cobra pilot turns away in disgust.

The club continues to fall to the ground, bumps a few times and then skids to a halt. After the Joes climb out with the rest of the civilians, Slipstream greets the Joes with a salute, which Dial-Tone returns. Holly walks up to Dial-Tone and tells him that he can forget about her previous statements about never having any fun on their dates. After Cindy throws her arms around Wet-Suit’s neck and asks if they could pick-up where they left off sometime, Wet-Suit happily replies, “Affirmative.” Madeline also throws her arms around Leatherneck and states he is a hero, and the Joe extends his arms out looks away from Madeline and asks himself, “Why me? Why me?”

At the Joes’ base, General Hawk states that it is a shame Cobra has the details for the nitrogen engine since, as stated by Dr. Mullaney, Cobra could perfect the device. However, Mainframes props his feet on the meeting table and explains that Cobra will not be able to figure out how the nitrogen engine works since Mainframe infected the disks containing the engine’s information with the computer virus Cobra developed during their Cobrathon a few months ago. As a result, the computer and the disks will be destroyed. And everyone in the room laughs at the irony of the moment.

Serpentor angrily states that Dr. Mullaney escaped again, but Dr. Mindbender points out that they have the nitrogen engine’s details and they can begin constructing a fleet of planes. However, the virus is activated and the two Cobra agents scramble for cover moments before the computer explodes. Serpentor then climbs out of the rubble and angrily yells, “They must pay! This I command!”
