Jake as a dragon is flying over New York City, talking over a walkie-talkie to Trixie, who passes it to Spud. Spud presses a button which made a traffic light turn red. After almost getting caught by the driver, Trixie remarks about how she and Spud were alike. Jake tells them to concentrate or they would not get yearbooks. They end up breaking into the van to steal three yearbooks.
The next day, Trixie and Spud are very happy about the yearbooks and Spud tell Trixie how much he likes the yearbook. Jake comes over and tells them because of dragon business, he missed Picture Day, and 9th grade dance and a lot more. Spud reassures him that it has been slow and if it stays that way, he will be able to get some yearbooks signed and attend a Make-Fun-of-Rotwood (the principal)-Party. Jake gets his hopes up… as Gramps calls to tell him that there was a magical emergency.
Jake rushes to Gramps’ shop to find out the emergency was only a test. He goes on to explain that he and Fu Dog are attending a three day Dragon Council Meeting. Sun says that he and Haley would be dragon training with her. Jake complains that the last week of middle school is now. Gramps refuses and yells at Fu Dog, who is trying to whack himself with a limbo stick.
Jake rushes into the gym to find everyone is with another person. Spud says that they are picking graduation partners. Jake asks if Danika Hunnicutt was open but Trixie says all the girls have been taken. Spud offers him a partner, which is CPR dummy. Jake complains that being the American Dragon makes him miss his normal life. Brad then goes to prank Rotwood, only to get suspended for the rest of middle school.
At lunch, the friends talk about Brad. Jake then says he has an idea and rushes home. Haley checks the rules, but finds out about Jake’s plan and threatens to call Gramps. Jake convinces her not to, saying she is next in line to be American Dragon if his plan works.
The Dragon Council talks to Jake after the cake explodes. As a result, Jake had his dragon chi taken for a week. Jake sees how cool it is to actually be a normal human being for one week. Back in New York, Councilor Chang and her sidekick, Bananas the monkey reveals their plan to make the Dark Dragon rise again.
Sun is preparing Haley to becoming the American Dragon. Haley claims that, unlike Jake, she will not let anyone down. Jake is apologizing to Gramps, with Gramps saying he is unable to understand how this could happen. Jake says it was a bad recipe and that he would act like a regular human. At Rotwood’s party, he teases him, with the kids saying that the imitation rocks.
Haley is practicing her duties. After going through one round, Sun says she needs to do it again… 199 times, that is. Jake and company are singing at Karaoke Night. At the same time, Haley is late for school and lies to her teacher on why she is late. Later, Haley has to find a troll’s wedding ring. She complains that the troll should be looking for it. At school, Jake loves the attention. After running into Danika Hunnicutt, she agrees to be her graduation partner, forgetting their previous encounter.
At night, Jonathan remarks on how calm Jake is compared to Haley, who is severely stressed out. After, she gets a call from Sun to tell her Chang is at the Magus Bazaar.
Chang is trying to find hydra scales and a phoenix feather. Sun and Haley attack them. Bananas poured Essence of Troll on Haley. Eventually, Chang defeats Sun and Banana finds the ingredients and the two escapes.
At the shop, half of Haley’s face looks like a troll. Fu and Gramps returned from the meet. Gramps says everything is Ok. Haley panics about her face. After researching, the four of them realize that hydra scales and a phoenix feather were needed, along with the American Dragon’s chi or blood to revive The Dark Dragon. However, Chang and Bananas were unaware that Haley was in place as the substitute American Dragon.
Jake runs to his house, only to be stopped by Danika Hunnicutt. She said that graduation uniforms were handed out early and that she picked up for him. Danika says it would be nice to move on to the next stages of their lives. Jake promises to be there and Danika leaves. Suddenly, Chang arrives. Jake forgot he was without dragon powers and Chang captured him.
Sun and Haley find Jake’s bag on the sidewalk. Gramps comments Jake should have been home hours ago. Haley accidentally tells Sun and Gramps of Jake’s plan. Grampa starts to go into a rant about how selfish and immature what Jake did was before Haley cuts him off, saying that they do not know how hard it is to be the American Dragon, she could not handle it even two more days let alone two years like Jake has. She lists all the sacrifices he had to make such as; saving magical creatures on a daily basis; lie to his own dad about who he is, say good-bye to the girl he loved, meaning Rose; while he may be the American Dragon, he is still a fourteen year old boy who wanted a few days to actually be a fourteen year old boy. Gramps sends Sun and Haley to rescue Jake and remarks that he has something to take care of.At the construction site shown earlier, Chang has Jake chained to a rock impressed by sphinx hair. Jake claims he has somewhere to go, but Chang does not really care. She pulls out the chi and finishes the potion. However, the Dark Dragon did not arise. She worked out that Jake's chi was that of his mere human side. Sun and Haley then attack. Haley frees Jake and Sun and Chang fight it out. Trixie calls saying that Danika was worried. Jake replies that he a bit busy now and asks to cover for him. Sun is eventually knocked out. As Chang is about to steal Haley’s chi, Gramps arrives and yells that Jake is the American Dragon, returning his dragon-side chi. Jake turns into a dragon and fights Chang. Bananas is about to help out by knocking Jake out with a crane, only to be defeated by Haley. As a result, the two are defeated and they flee to a tunnel, where rocks trap them, but the hook scrapes Jake.
Later, after Sun bandaged Jake's wound Gramps says he is cutting dragon training in half, going to explain that he is only fourteen and deserves some time to hang with his friends. Haley can fill in and the four fly to graduation.
Meanwhile, Jake’s blood falls into the incomplete potion, with the Dark Dragon rising again.
The battle against Chang
- Haley: (accidentally tells Jake's plan) Oh look, azaleas are in bloom.
- Lao Shi: PRANK?!
- Sun: Jake ditched his American Dragon duties on purpose?
- Lao Shi: (shouting in Chinese) Ihya asamiowa! Of all the immature self-serving...
- Haley: HEY! When was the last time either of you were the American Dragon?! (Lao Shi and Sun look shocked) Well as the little troll girl currently filling the position, let me tell you its stinkin hard! I can't imagine it doing it 2 more days, let alone 2 more years. And to think about everything Jake's gone through: he's had to save magical creatures on a daily basis, lie to his own dad about who he is, say good-bye to the girl he loved, all to protect a mystical world that nobody knows about! He may be the American Dragon, but he's also a 14 year old kid who just wanted a couple days off. If that makes him immature, fine. But self-serving? With all due respect to both of you... STEP OFF! (Sun and Lao Shi are speechless) Heh, I crossed the line with that step off part didn't I?
- Lao Shi: Sun, you and Haley track down Chang and rescue Jake.
- Sun: But Lao Shi, what about you?
- Lao Shi: I have something to take care of.
- (scene cuts Jake being held hostage in a chain with sphinx hair by Chang)
- (Bananas B pours Hydra Scales in the fire)
- Jake Long: (struggles with chains) Yo Chang, nothing personal, but I kinda got someplace to be. So if you don't mind...
- Chang: SILENCE! These chains are reinforced with sphinx hair, rendering you powerless. In the mean time the chi of the American Dragon is mine.
- (Chang takes out Jake's chi and she throws it in to the fire)
- Bananas B: Yo, Changetty-Chang. (gives Chang the Phoenix Feather) Say dem magic words.
- Chang: (goes to the fire) And with the drop of a Phoenix Feather: The Dragon of Darkness shall rise from the ashes. (drops the Phoenix Feather in the fire and nothing happens)
- Jake: Okay, not a bad show. But the ending isn't really living up to the hype. Can I go now?
- Chang: SILENCE! Why didn't the spell work? Wait... Jake's chi should have taken dragon form.
- Bananas B: What are you sayin' den? He's not a dragon? 'Cause that would mean...
- Haley Long: That you answer to me! Ya heard.
- (Sun Park breaths fire at Chang and Haley frees Jake)
- Jake: Haley? Ughh... What happened to your face?
- Haley: (shows her troll face)
- Jake: (hears his phone) Never mind cover me for a sec.
- Haley: It's what I do. HIYA!
- Trixie: (on the phone) Yo Jakey, where are you? Graduation's about to start and Danica's been asking about you.
- Jake: (on the phone) Running a little late, but hey it's what I do. You and Spud cool to...
- Trixie: Cover for you? Hey baby, it's what we do. (hangs up) Heyy yo stop the music! (steps up to the podium) Give a warm welcome to Arthur Spudinski and his...um...comedy stylings.
- Spud: (pulled onstage) Waaah. Umm...oh...hi. (make fart noises with his armpit & starts playing a tune)
- (scene cuts back to the battle)
- Chang: Sun Park? I thought you were all about peace and love.
- Sun Park: And what I'd really love is to give you a peace of THIS! (tries to hit Chang, but Chang grabs her tail and throws her) Woah!
- (Sun gets thrown and its a rock and gets knocked out)
- Jake and Haley: Sun!
- Chang: So, I'm thinking Jake Long is no longer the American Dragon. And since his little sister is next in line that would mean you've got something I want.
- Jake: Leave her alone, Chang!
- (Chang knocks Jake out of the way)
- Chang: Pathetic human. Who are you to tell me what to do?
- (Lao Shi arrives with the dragon chi)
- Lao Shi: His name is Jake Long! And he is the American Dragon! Hiya! (throws the dragon chi at Jake and he transforms into the American Dragon)
- Jake: My dragon chi. But Gramps, how did you...
- Lao Shi: An early graduation gift from the Dragon Council. You've earned it.
- Chang: How very touching? Unfortunately that chi is mine! (fires a magenta claw beam and tries to get the chi, but Jake blasts it with his fire)
- (Bananas B goes to the giant machine to hit Jake with the giant hook)
- Bananas B: Don't worry, Chang. I'll save ya. (pulls the levers on in the machine)
- Haley: Not today, Monkey! Haa! (jumps on Bananas B)
- Bananas B: Outta my way, you Bugly Troll Girl!
- (the machine hits the cliff edge and rocks fall on Chang)
- Lao Shi: Jake! Look out!
- (the giant hook scratches Jake's arm)
- Jake: YOW!
- Haley: Hiya!! (Haley kicks Bananas B off the machine)
- Jake: You know what Chang? Being the American Dragon, kinda rocks. Oh and speaking of rocks...
- Chang: (sees the rocks falling) What? NOOOOOOOOOOOOOOOOO!
- (Chang and Bananas B run inside a cave and the rocks trap them)
The Dark Dragon Returns
- Lao Shi: Come young dragon, we have a graduation to attend.
- (Jake, Sun, Lao Shi, and Haley transform into dragons and fly off)
- Jake: So there you have it; the week that I wasn't the American Dragon. That night at graduation I got to thinking. Being human was a wake up call. (Jake remembers the time when he battled the Guardian Serpent, the Moss Monster, 88 and 89, rescuing Fu from falling, and opens locker with dragon claw) Sure there had been some tough times, but having magical powers has kinda rocked. And not just in a saving the people I care about kind of way but in a cool everyday kind of way too. I mean, don't get me wrong; having a secret, double life is always going to be a balancing act. (Rotwood gives Spud, Trixie, and Jake there rewards) But with the help of my friends and family...
- (Susan, Johnathan, and Haley Long, Lao Shi, Sun Park, and Fu Dog cheering for Jake)
- Johnathan Long: Way to go Jakers!
- Jake: I know I can totally face anything life throws at me. (Jake and his friends throw there hats in the air)
- (Jake's dragon blood on the hook drips onto the ashes and the ground opens with the Dark Dragon rising)
- Dark Dragon: RAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAOOOOOOOOR!
