After receiving a super-exclusive ticket to Adrenaland, Ben leaves behind Grandpa Max and Gwen to enjoy the perks of being the park's only attendant, but when he learns he's not alone, our hero must now contend with the only kid who could afford the price of admission: Billy Billions!
The episode opens up with Billy Billions meeting with Forever Knight. Billy Billions states that whatever is going on, better be interesting. Forever Knight explains that it involves a certain nemesis of his - Ben. Billy gets angered as he hears that name. Forever Knight states that he needs Billy to go fetch Ben for him. Billy states that he's no dog. Forever Knight knows he won't work for free, and overs him tickets to a highly exclusive Adrenaland Park on a private island. He also states that he knows someone else who already has access. Billy gets angry, and questions who.
On the island, Ben gets excited about Adrenaland. Gwen gets jealous of Ben getting to go. Max tries to cheer Gwen up. The workers come and collect Ben. Max and Gwen goes to stand in the line, which is extremely long. One of the workers gives him options to dress. He dresses up with a tuxedo and top hat. Ben walks through the park, and notices a line. He questions what a line is doing there, since the island is super exclusive. The worker explains that they're holograms. Ben then sees a hologram of himself. Ben finds it creepy. The workers carry Ben up to the ride. Ben gets on a drop tower, and prepares to take a picture of how fancy it is. Then the ride is shot with a laser.
Back outside the park, Gwen waits to be angry at Ben later. Max states that the line hasn't moved in an hour. The two go to find the manager to see what's going on. They walk up to one of the employees, who happens to be standing near an employee only door. The employee questions if they are the two mascots. Max begins to deny that, but Gwen tells him to play along. They walk inside before they miss the orientation. Max and Gwen sits down next to a bored lady, and a screen plays, telling them about Galahad, Inc. Gwen then gets messages from Ben, showing that he's in danger. Max asks to leave, because of a family emergency. The lady sitting next to them, with a completely changed attitude, tells them Galahad is their family, and the two are surrounded by the workers.
On the ride, Ben transforms into XLR8, and tries to outrun the drones. He notices that Billy is behind it. In the presentation room, the show ends. Luckily, Max and Gwen were wearing earplugs. Before they try to leave, they are forced to wear mascot costumes. XLR8 runs away from Billy, but soon times out. Ben hides while Billy searches him. Ben's watch times in, and he transforms into Four Arms. He begins to fight off Billy on top of another ride. He times out and again and they wrestle. They land inside a rollercoaster, and ride around the park. Ben shows Billy the pictures of them having fun, and Billy destroys them. Ben transforms into Cannonbolt and rolls around the park. He uses a waterslide to his advantage and destroys Billy's drones. Ben rolls around going on every single ride. This angers Billy. Ben times out again, and runs towards Billy. Billy pushes him on the ground stating that his entire day is ruined. Billy states that he owns everything, and he now owns Ben, and no one can help him. Then, a horse mascot comes in, clearing anything in its path. Billy orders the employees to stop it, but they fail. The mascot picks up Ben, and reveals to be Max and Gwen. Billy questions how they plan on stopping his mind controlled workers. Gwen tells them that they aren't getting paid, and they employees walk off. Billy prepares to summon his drones with his tablet, but Max slams it on the ground, destroying it.
Billy states he doesn't know how Ben does it. Even when Billy has everything, Ben still to take it away. Ben explains that it's better to share stuff than keep it to yourself, and he had more fun sharing the park with him. Billy considers hanging with the Tennysons, then he thinks back to Forever Knight. He is then grossed by his choice to consider going with the Tennysons, and he calls him butler, and they walk off. Gwen asks Ben if being rich wasn't everything he thought it would be. Ben explains that he will never be spoiled like Billy. Max then states that they have a whole park to explore.
Billy: Well? Forever Knight: Come in, Billy. Billy: My time is valuable, so this better be interesting. Forever Knight: Oh, I think it is. You see, this involves a certain nemesis of yours -- Tennyson. I need you to fetch him for me. Billy: Fetch? Billy Billions is not your dog! Forever Knight: I don't expect you to do it for free. Billy Billions: Oh, and what could you possibly offer me? Cash, minions, power? The realistic holograms in place of human affection? Forever Knight: How about tickets to a highly exclusive Adrenaland Park on a private island? Admission is extremely limited. Even the elite must wait in line. Now, this ticket has your name on it, but I know of someone else who's already received his. Billy: Who's the other person?
Narrator: Welcome to Galahad, Inc., acquisition experts. Laser Town, Pancake Palace, and now, Adrenaland. But today, we acquire the most important property of all -- you! The more we acquire, the more we connect. Galahad, Inc. is like a family. Remember your family? That's good. Gwen: Ugh! What down? (Gasp). Grandpa! Ben is in trouble. Max: Family... Gwen: Look! Max: (Gasp). Ben! We have to help him. Excuse me. We need to leave. A family emergency. Woman: But Galahad, Inc. is our family. Employee: She's right, you know.
Billy: You soiled every ride with your filth. My entire day is ruined. You think you can just walk in like you own the place? You don't own anything. But I do! I own those drones! I own these mind-controlled peons, and now I'm going to own you! And there's no one who's going to bail you out!
Billy: I don't know how you do it, Tennyson. Even when I have everything, you still manage to take it away from me. Ben: Maybe because it's better to share stuff than be alone. Billy: Hm. Explain. Ben: Dude, I had more fun sharing pictures of the park than keeping it to myself. I even had fun sharing the coaster with you. You get what I mean? Billy: I think I get it, but wait. Let me think this over. Hmm. (Thinks of Forever Knight and money, then looks at the Tennysons). Eww! I can't believe I was about to consider that. (Claps). Billy's Butler: Yes, Master Billions? Billy: Take me home before I follow through with charity work.
