With their chores finished, Miko is looking forward to doing some "dune bashing" with Bulkhead, but he'd rather check out the monster truck rally in town. Their plans are interrupted when Ratchet receives a signal from a starship headed for Earth. Arcee wonders if it might be a Decepticon trap, but Bulkhead identifies the incoming Autobot as his old friend and Wrecker pal, Wheeljack. Optimus sends landing coordinates for Wheeljack's landing on the next day, and Bulkhead is excited to see his old friend.
On the Decepticon ship, Soundwave has monitored the conversation and it gives Starscream the chance he needs. He orders Makeshift, a Decepticon with the ability to take on the appearance and voice of any Cybertronian he picks, to prepare for a mission.
The kids are excited to be getting to meet a new Autobot. Ratchet has problems getting the Ground Bridge working, due to the damage sustained during the Scraplet infestation. Their instruments pick up Decepticon signals closing on the Jackhammer. Indeed, the Vehicons manage to shoot down the ship, but Wheeljack emerges from the wreckage and starts smashing the tar out of them. Ratchet finally gets the Ground Bridge operational, and Bulkhead, Arcee and Bumblebee storm through to find Wheeljack knocks down the last of the 'cons wo was standing. Bulkhead greets his old friend with a massive bear hug, and the four Autobots return to base. Wheeljack hits it off with Miko right away, and checks in with Optimus. Ratchet's not as enthusiastic as the others with Bulkhead's friend, as he senses impending destruction.
Starscream discusses their success in getting a spy into the Autobot base as he and Soundwave pay a visit to their prisoner — the real Wheeljack. Now he's inside the Autobot base, Makeshift will be able to activate the Ground Bridge and reveal the base's location so Starscream can send the troops in. Wheeljack mocks Starscream, who's prevented from killing the prisoner by Soundwave since Wheeljack may yet be of use.
The Autobots and kids celebrate Wheeljack's arrival, Miko by breaking out her electric guitar and Bulkhead and "Wheeljack" by engaging in some Lobbing. After some encouragement by Miko, Raf busts some dance moves by doing The Robot, and Bumblebee joins in. Makeshift takes some time to fish for info on the Ground Bridge from Ratchet, who says it's in the middle of defragging and can't be used for a few hours.
Starscream wonders why Makeshift is taking so long to get the Ground Bridge activated, since he won't be able to keep the Autobots fooled for long.
Bulkhead tells the kids about a battle he and Wheeljack took part in, and Makeshift barely covers for his lack of knowledge. Bulkhead observes that his old friend seems different, but Makeshift writes this off as jet lag, and asks Miko to show him around the base. However Bulkhead's suspicions have been raised, and Arcee's suggestions don't alleviate them.
On the Decepticon ship, Wheeljack manages to kill his guard and get free from his bonds.
Miko wanders the base with Makeshift, and the 'con manages to get the location of the Autobot base out of her. Miko promises to show him the way out, and they return to the control center, where Bulkhead asks his "friend" to tell the story of the Battle of Darkmount Pass. Makeshift tells the story, but manages to get one crucial detail wrong — Bulkhead wasn't part of the battle. Realizing that his cover's blown, Makeshift takes Miko hostage.
Starscream and Soundwave hang out on top of the Decepticon ship with a bunch of Vehicons, waiting for Makeshift to open the Ground Bridge. They're confronted by Wheeljack, who fights his way through a bunch of Vehicons and pounces on Starscream. As more 'cons rush towards Wheeljack, the Ground Bridge activates, courtesy of Makeshift. Makeshift was ready to enter the Ground Bridge on the Autobot end, when Wheeljack comes flying through it and lands on him. Ratchet shuts down the Ground Bridge before any Decepticons come through. The two Wheeljacks draw their swords and fight at length while the Autobots fail to keep track of who's who. Wheeljack, of course, triumphs.
Starscream is pleased when the Ground Bridge opens again and orders the Vehicons through, however it's only been reopened so Bulkhead can throw Makeshift through. The 'con lands on Starscream, who asks if Makeshift has obtained the location of the Autobot base. Makeshift was in the process of telling him when Starscream realizes that the grenade Makeshift is wearing has been primed and is about to explode, and he and Soundwave retreat, leaving Makeshift and a number of Vehicons to die in the ensuing explosion.
The Autobots have another party, to Ratchet's dismay. Bulkhead suggests they pick out a vehicle mode for Wheeljack, but Wheeljack says he's not staying now that his ship's fixed. The next morning, he offers to take Bulkhead with him, but Bulkhead's too attached to Earth and Miko to leave. Miko snaps a picture of the two Autobots with her cell phone before Wheeljack leaves.

- When the camera angle moves to show Optimus saying that he knows Wheeljack by reputation only, the shadow of Miko's heel looks lightly separated from it, as if her leg were hovering over Bulkhead's armour plate.
- Apparently, huge, alien robots can leave their tracks in the snow (see Bumblebee and Bulkhead at the beginning of the previous episode), but it looks like they cannot leave any in the sand.
- Part of Wheeljack's right arm goes through his chest as he was preparing for battle on top of the Nemesis.
- When the alarm goes off, the monitor shows five bogies (Vehicons) approaching Wheeljack's ship. But in the next scene, when Wheeljack's ship is being attacked, there are six Vehicons.
- The Autobots refer to their base as "Autobot Outpost Omega One", the first time the base is named on-screen.

- Wheeljack and Bulkhead are former members of the Wreckers. This is the team's first mention in a TV series.

- Starscream once again attempts to kill a prisoner (Wheeljack) the moment they insinuate he isn't in charge. Only this time, he is stopped by Soundwave.
- Bulkhead mentions that Wheeljack has a public service record. Presumably, this is true for all Autobots in the military.
- While Skyquake was the first character shown with a hand-held gun, Wheeljack is the first one shown with a pair of hand-held melee weapons (in this case, two swords).
- Adaptations of this episode include a storybook for younger readers titled Decepticon in Disguise.
