While visiting China, Ben, Gwen, and Max take a trek to the Great Wall, but their adventures is nearly ruined by daredevils LaGrange and Vin Ethanol trying to jump the international monument, and Ben must hop into the Rustbuggy to chase away the fast and furious foes.
The episode opens up with the Tennysons at the Great Wall of China. Max looks around at the scenery. ben questions what's taking so long, as he wants to see sights really fast. Ben prepares to call up the Rustbuggy with the app Phil made. Gwen tells Ben that he can't do alien stuff all over the wall, as it is centuries old and he could damage it. Ben listens, and decides to see the whole wall by running.
Eventually, ben is tired out by the long running. He looks up to see the wall going on for even longer. Gwen and Max walks, and they notice beautiful fireworks. Gwen wonders if ben sees all of this. Ben complains about not being able to use the Rustbuggy, and then he hears an engine start up. He looks over the wall to see one of the "coolest car he's ever seen". Vin Ethanol closes the hood, and thanks Ben, complimenting him that he has good taste. Ben questions if Vin is supposed to be in jail, and did he break out. Vin tells him that all he got was community service, and the community is like family, and nothing is more important to him than family. Vin allows Ben to tough the car, and he explains the specs. Vin states that a lot of hard work and patients went into his car, and if Ben starts now he could build one like it by the time he's old enough to drive. He then shows ben how to change a tire. LaGrange pulls up after, and greets the two. Ben questions what LaGrange is doing in China. LaGrange explains that he and Vin are going to race and jump the great wall. Ben is amazed by the idea, however, he isn't going to let them do it. LaGrange challenges him to try and stop him, and he hops in his car. Ben states that he and Vin are gonna stop LaGrange. However, Vin gets in his car and drives off. Ben transforms into Slapback and attempts to stop them. With the help of Vin, they manage to shake Ben off. The two begin the race, and Ben times out. Ben calls in Glitch for assistance. The Omnitrix times back in, and Ben transforms into Heatblast. The Rustbuggy transforms as well. Heatblast and Glitch catches up to them. Heatblast states that whatever they're doing isn't worth all the damage they're causing. Vin agrees with Ben, as he just wants a clean race. Heatblast then accelerates to catch up with them. Heatblast begins firing, and LaGrange begs Vin to help, stating that they were family once. Vin pulls down his car visor, and looks at a bunch of images of him, LaGrange, Dirty Dobs, and the Malachi Sisters. He then decides to help him. Vin rams into the Rustbuggy, and Ben times out. Glitch is no damaged.
Max and Gwen continues to walk across the Great Wall. Max then hears cars. Gwen takes the binoculars and looks over the wall. She spots LaGrange's car with Vin on his tail. She then calls Ben on the phone, and tries to inform him. Ben states that he already ran into them. Gwen tells them that they were driving through a town. Ben tells her about their plan to jump the wall. Gwen states that it would end poorly, and they'd end up destroying the wall hurting lots of people. LaGrange and Vin are now heading Ben's way near the wall. Ben uses Four Arms and tries to stop their path. LaGrange uses his car to flip Vin's car over into Four Arms. Four Arms convinces Vin to help him stop LaGrange to save people from getting hurt. LaGrange looks back, and he sees Four Arms and Vin pulling up. LaGrange boosts his car, and speeds up. Vin pulls out a power source to speed up his vehicle. Four Arms struggles to hold on. As LaGrange gets closer to the wall, Ben and Vin catches up. LaGrange speeds up once again. Vin breaks it to Four Arms that his car can't take much more of this. Four Arms asks for another nitro tank. Four Arms uses it to catch up to LaGrange, and stop his car. The ramp then easily breaks without them even ramping it. LaGrange wines that he didn't get to jump the Wall, and Four Arms throws him over.
Vin drives Ben to Max and Gwen, and Ben tells them about everything. Vin compliments Ben on keeping his cool, and he admires Max for raising a good family. Vin then goes to drop LaGrange off at the police station.
It is revealed that Glitch can transform his vehicle form based on the Omnitrix aliens.
Gwen: What a breathtaking view. Don't you think, Grandpa? Max: Ah, now that's the stuff... dumplings. Ben: Why do we keep stopping? I'm going to be as old as you by the time we finish. Max: First of all, rude. Second of all, you need to learn to take your time, Ben. You can see more sights at a reasonable speed. Ben: Well, I enjoy sights at super speed, and I know just the alien to run with. Gwen: Your phone? Ben: With the app Phil made, I can call the Rustbuggy in no time. (Gwen turns phone off). Hey, what gives? Gwen: Ben, you can't do alien stuff all over the wall. It's centuries old. You could damage it. Ben: ugh, fine, but you guys are moving so slow you'll never see the whole wall. I plan on seeing the whole thing. (Starts running) Gwen: Do you think ben knows the Wall is 5,000 miles long? Max: I guess we'll find out.
Ben: Man, I can't use the Rustbuggy. Nobody wants me to have fun. (Engine starts). That was fast. (Looks over the wall)(Gasp). Whoa. That's the coolest car I've ever seen. Vin: Thanks, kid. You got good taste. Ben: You! Vin: (Chuckles). Yeah, Vin Ethanol, in the flesh. Ben: Aren't you supposed to be in jail? Did you break out? Vin: Jail? Nah, I just got community service. Ben: Oh. Well, did you finish it? Vin: Of course I finished it. The community is like family, and nothing is more important to me than family. Ben: That sounds like a not-bad-guy thing to do. Vin: (Chuckles). Look, if you want to tough the car, go ahead. Ben: Ha ha! Yes! Vin: A good set of wheels is like one of the family. Suited her up with a heat-resistant carbon-fiber body, pushrod suspension with anti-dive geometry, backup tank of my special E-100. This is some serious family-style speed. And a twin-turbo V-12 engine. Ben: So those are a lot of words to say it goes fast, right? Vin: (Laughs) A lot of hard work and patience went into this car. Start now, and you could build one like it by the time you're old enough to drive. Come on. Let me show you how to change a tire. You ain't gonna understand the rush you get fixing up a car til' you get your hands dirty.
LaGrange: Ha, ha, Tennyson. How interesting it is to see you here. Vin: LaGrange. Ben: What are you doing doing in China? LaGrange: Ho, ho, ho, ho. I'm surprised your vascular friend did not inform you. Today, Vin Ethanol and myself race to jump the Great Wall!
Vin: Nothing personal, Tennyson. Family just comes first.
Vin: Good to have old, LaGrange, back. Feels like we're finally racing for real. LaGrange: Ugh. Now if I could just find a way to shake you.
Four Arms: Vin, we need to talk, we don't have much time. Uh, are you okay? Vin: (Growls in anger). (Yells). That low-life buster pulls this every time. I'm so mad I feel like I could rip a door off a car! (Points to his car). But not that car 'cause I love it.
LaGrange: (Cries). I was so close to jumping the Wall! Four Arms: I think we could work something out. (Four Arms throws LaGrange over the Wall) LaGrange: Aah! Ugh!
Vin: Hey, kid, you really kept your cool back there. Ben: (Gasp). I'm cool? Gwen: He said you kept cool, not you are cool. Vin: (Points to Max) And you, you're raising a great family. Max: Oh, gee, thanks. Not sure how to take that coming from a criminal, but I appreciate it. Vin: Now excuse me while I drop this buster off at the police station. Peace.
The episode's title is a play on "la Grande Muraille", which is French for "the Great Wall".
One of the shots in the episode was inspired by a shot in the movie Redline.[ALM 1]
LaGrange's first name was revealed to be, Lucien, in a storyboard for this episode.
Kelly Turnbull, who pitched this episode to the director, was glad the crew kept Vin's collection of polaroids of his pals that he uses to remind himself LaGrange is his BFF when the latter does jerk friend things like asking him to drive Heatblast and Glitch off the road.[KT 1]
