The story begins on a rainy night at the castle and we see inside the castle as the credits roll till we zoom into a door until a monster tears the doors open and gets to Mystery Inc. and Fred, Lukas, Daphne, and Velma run to the left. Shaggy and Scooby scream and they run in different directions.

Shaggy: YIKES!!!

He goes to a room, locks the door behind him, and goes to the other door to get away the monster is in front of the door and Shaggy tries to get out the door he locked but he pulls out the doorknob and runs off.

Shaggy Rogers: Scooby-Doo! Where are you?

He runs and bumps into Scooby, and then the "Scooby-Doo! Where Are You" theme song [song by Third Eye Blind] plays.

Shaggy runs with Scooby on his back and the moat monster stops they turn around and run with the rug in waves as the monster slashes through and chases the duo. Scooby rides on Scooby as the monster chases them and Shaggy lifts the shield to block him, but the monster smashes it down. And they come across a table and Shaggy slides throw, and gets on Scooby's back again, as they go throw the door. As they go into a Scooby-Dooby-Door chase, but the monster doesn't go after them.

As Fred, Lukas, Daphne, and Velma arrive, the monster grabs the shield and throws it like a frisbee at them, and they run out of they as it breaks through the window. And they run out of the pathway and Daphne and Velma fall as Fred and Lukas catch them. And they hold on to his hands and the monster comes to Fred and slashes Fred's shirt as Velma lets go of Fred's hand and catches on to Daphne's leg, and Scooby falls into the monster's arms and gets scared and goes sliding on the stair rail and the monster chases him down the steps as the song ends.

Then, Scooby lands on the empty knight's armor, and the rest fall like dominoes, and one lands on the moat monster. Shaggy Fred and Lukas help Velma and Daphne up and Velma unmasks the monster.

Shaggy Rogers: Like, it's Mr. Beeman, the real estate agent.

Scooby-Doo: Rr. Reeran?

Lukas: Who would've thought?

Velma Dinkley: Yeah, he was printing millions of counterfeit dollars in the basement with his printing press. What we originally thought was mold was green ink. See?

Mr. Beeman: I would've gotten away with it, too if it wasn't for that big dog and you meddling kids!

Scooby gets the mask but then scares himself.

Later, the mystery turns out to be a story by Daphne Blake in a live television show.

Daphne Blake: And that's how we solved the case of the moat monster. One of our most frightening mysteries.

Chris: Stories like that always give me the heebie-jeebies. No wonder you became a reporter. That Moat Monster almost sliced you up like a pepperoni pizza. And then we wouldn't have Coast to Coast with Daphne Blake your very successful syndicated series on Americana. Going on its second season, I might add. I never miss it.

Daphne Blake: Thanks, Chris. You know, the real reason I changed jobs was because the monsters and ghosts always turned out to be bad guys in masks.

Chris: Got a little boring, eh?

Daphne Blake: No kidding. In fact, that's why the gang went their separate ways except for Fred and me.

Chris: She means Fred Jones, who's now the producer and one-man crew of Daphne's show. How about getting a shot of Freddy, guys?

They got a shot of Fred, and the audience applauded.

Chris: Is he cute or what? So what's coming up for the new season?

Daphne Blake: A new series of segments called Haunted America.

Chris: Sort of a Ghost to Ghost with Daphne Blake?

Daphne Blake: Right, but this time I intend to find some real haunted houses for my viewers.

Chris: It's too bad the rest of the old gang won't be along for the ride.

Daphne Blake: Yeah, I miss them.

At the airport

Shaggy Rogers: Yeah, like we miss you too, Daphne.

Scooby-Doo: Reah. (Sniffened)

Chris: Don't go away, we'll be right back with Daphne Blake.

Airport boss: Hey you two! Get back to work!

Shaggy Rogers: Like, we're right on it, boss man sir.

Scooby-Doo: Ruh-huh.

They looked through the luggage as Scooby got a scent of something.

Shaggy Rogers: Got something, Scoob?

Scooby-Doo: Reah. (sniffs some more) Reah, reah. (goes through the suitcase but ends up with a sock on the top of his nose, which makes him sneeze)

Shaggy Rogers: Eh, no offense, old buddy. But I think your nose might be losing its touch.

Scooby-Doo: Ruh-uh.

(He goes through again and then finds cheese)

Shaggy Rogers: Very sneaky, but they can't fool your nose.

Scooby-Doo: That's right.

Shaggy Rogers: No one brings contraband food into our country with us on the job!
Scooby-Doo: Ruh-uh.

Shaggy Rogers: Let's go check it in, Scoob!

They went inside the contraband storage room and were amazed to see all the food inside.

Shaggy Rogers: Is this the jackpot of jobs or what?

Scooby-Doo: (laughs) Reah!

At the bookstore.

Velma Dinkley: Yes, we do carry the Hair Raisers series. Number 23, The Vampire Village? Got it. Number 24, The Creepy Clown Town? Got it. Number 25, Menace At Mummy Manor? Got it. Yes, I'll hold them till Tuesday. Two weeks from Tuesday? Yeah, that's fine. 'Bye. (Hangs up the phone) Solving mysteries was a lot more fun than selling them.

The phone rings and Velma answers it.

Velma Dinkley: Mystery Ink Bookshop. Freddy? Jinkies! Sounds great. Count me in.

At Coolsville University.

Lukas was presenting his latest invention in front of the class.

Lukas: And not enough, this releases the amount of frequency produced from the coils as it would even cause hovering, like so.

He turns on the switch as he drops the ball at the center before it is stopped by electricity.

Students: [Intrigued]

Lukas: See? Not even Isaac Newton can pull that off if it wasn't for the apple.

[Bell rings]

Teacher: Alright, class, that's the bell. See you all soon.

The students pack up their stuff and leave the room, while Lukas puts the experiment away. Then, he gets a phone call.

Lukas: [answers it] Hello? Fred. Long time no see. Are you serious? I'm in.

Inside of Lukas' backpack, there is a picture. The picture shows an elderly man with white hair, holding a young child in his hands.

On the streets of Coolsville, Lukas leaves the building as he looks up.

Lukas: Wonder what he had in store.

Lukas sees an antique shop. He walks inside and sees ancient artifacts.

Lukas: Hello? Grandpa? It's Lukas.

???: Come inside, Lukas, I'm at the back.

Lukas walks inside the back room. He enters the backroom, which has many odd objects, and sees a man on the chair with a big book in his hand while having a cup of tea in his other hand.

The man appears to be a thousand years old since he hasn't aged. Having pure white hair, and the normal wrinkles of an old man, wears a button shirt with no tie, ankle-length pants with lines across, grey shoes, and a ring on his finger.

???: So, how's my favorite grandson?

Lukas: I did well, including with my presentation.

???: That's good. What else?

Lukas: My friend, Fred, called.

???: Really? And what did he say?

Lukas: He said that there's a mystery somewhere in New Orleans, as he is bringing back the others.

Lukas' grandfather closes the book.

Grandfather: Is that so?

Lukas: Yes. The gang is getting back together.

He gets up as he has shown to be taller and slim, walking towards the bookcase and placing it in.

Grandfather: Been a long time since you and your friends were together again, since high school, now this is happening, this seems to be big to you, my grandson.

Lukas: Yeah. I know.

Grandfather: Before you head out, [reaches for the duffel bag, placing different items inside] here are some essentials before traveling to Orleans.

Lukas: Extra clothes. Toothbrush. Toothpaste. Mouthwash. Deodorant. Biology, physics, and math books The Encantus. Wait...

Lukas pulls out a magic book called Encantus.

Grandfather: Wouldn't forget the old reliable.

Lukas then sees a glowing green ring. Lukas slowly reaches for it, as it glows brighter.

The ring is the shape of a dragon. It somehow starts to move on its own, before the head makes a tiny roar, and wraps around Lukas' finger, forming into a ring.

Lukas: You're giving me your ring?

Grandfather: I had that ring for a long time, longer when I was raising you, now it's time I give you my ring, as you are ready.

Lukas: [hugs his grandfather] Thanks, Grandpa Merlin.

Merlin smiles as he returns the hug.

Merlin: You're welcome, Lukas.

Lukas: Well, gotta go. I'll keep in touch with you and Mom and Dad.

Later the Airport Manager came into the contraband storage. When he walks in, he exclaims "D'oh!" when he is surprised that Shaggy and Scooby had eaten the food with full stomachs)

Shaggy Rogers: Like Hi, Boss.

Airport boss: You... You.. You ate all the contraband!

Scooby-Doo: (burps) R'excuse me. (Giggles)

Shaggy Rogers: Like, untrue, boss. We didn't eat it all. There's still a couple of gorgonzolas left. Help yourself.

Airport boss: You're a couple of Gorgonzolas! You're fired!

He leaves angrily and slams the door.

Shaggy Rogers: Sheesh, like what a grouch! Looks like we are unemployed again, old pal.

Scooby-Doo: Reah! Runemployed! (Cries and blows his nose)

Shaggy Rogers: Like, take it easy, buddy. Something will turn up. So what if this was the greatest gig ever? So what if we starve? Turn to skin and bones.

They cry and the phone rings.

Shaggy Rogers: Like, Hello. Freddy? Zoinks! We just caught you on the tube! Busy? Nah. Scoob and I were just thinking of taking some time off!

Scooby-Doo: Yeah! Yeah!
