It's Christmas at Royal Wood. All of them celebrate with joy with their families.
"? Merry Christmas! This is the most beautiful of years" Tom chants.
"?Christmas most beautiful years to be with his families.?" Sabine chant.
Marinette and her parents made Christmas logs. They distribute it to people.
"? Merry Christmas, Mrs. Cheryl and Meryl.? ﾽ Marinette gives one to the school secretary and her sister.
Both identical women received one.
"? Merry Christmas." Cheryl and Meryl sing together.
"? Merry Christmas, Mr. Loud and Lisa?￢ﾀﾝ Marinette hands Lynn Senior a.
"Thank you very much and merry christmas."
The next client is Adrien's bodyguard gorilla. Marinette would have preferred to be Adrien who is coming.
The next customer who comes to the house is Clyde and his father, Harold.
"? Merry Christmas Clyde and Mr. Mcbride?"
"? Merry Christmas to you too"
They continue to distribute Christmas logs to other customers.
The scene changes for the Agreste mansion. Adrien is alone at the kitchen table and he eats alone.
"Father is not coming?" Adrien asks Nathalie.
"Sorry your father is busy…"
"I see. I am going to eat in my room." The blond boy said in a sad voice.
Adrien goes to his room.
"Let's go Plagg, get some air. Claw up!"
"Wait, could I at least eat a camombelle?…."
The Kwami Chat is sucked into the joke, Adrien turns into Chat Noir. He goes out the window.
Cat Noir comes out and jumps from house to house.
"? It's the worst evening for me. I am always alone at each Christmas. ? Sometimes I envy the families who are together for the holidays ?"
He looks at the windows, the families who are together during this feast. Cat Noir feels very sad and needs to release his anger.
He stops in front of the huge fir tree in the city.
"Cataclysm!" His hand is concentrated with destructive energy and rushes forward but the memory of his mother appears.
Cat Noir stops and uses his power on a bus stop bench.
"Plagg, Claw Off!"
The Kwami Cat comes out of the ring and falls on the snow.
"Plagg! Plagg ?!"
"?I feel exhausted, I'm too hungry and on an empty stomach?"
"Sorry Plagg, because of my frustration. I didn't think about you. Come home to recover your strength."
Adrien takes Plagg and takes the direction of his house.
During this time. Gabriel goes to see his son in his room but Adrien is no longer there.
"Where is my son! Look for him immediately!"
Nathalie and the gorilla go in search of Adrien. The disappearance of the boy was heard by everyone.
Everyone will help find Gabriel Agreste's son.
"Adrien is gone. Ladybug will help too."
Marinette turns into Ladybug, she crosses the Ace of King.
"Ladybug, what are you doing here?"
"Adrien is missing. I went to find him."
"Separate us, each on our side We will have a chance to find him."
"Good idea."
The two heroes disperse to seek more land.
Elsewhere, Adrien is walking in the snow, he is carrying his exhausted Kwami and the two are really cold.
Further on, he sees two children annoying a man disguised as Santa Claus.
"Hey! Leave him alone! If you keep going, you might be on the bad kids list."
The two children leave the gentleman dressed in red alone.
"Everything is fine?"
"Yes, thank you. In your day, the children do not respect their elders. Tell me young man, what are you doing outside? It's cold."
"I went out to look for a last minute present."
"I see. You better be it's you. I'm sure your parents must be worried about you."
"Yes, you are probably right."
"I'll bring you."
"By any chance, you don't have a Camembert?"
"Exactly what I have in my sandwich." He gives the cheese of his sandwich to Adrien.
The blond boy shares distractedly with his Kwami.
Santa Claus brings Adrien home. Elsewhere, Ace of King contracts Ladybug.
[Ladybug. ]
"Did you find Adrien?"
[No, but I found this.] He sends the photo of the dusty bus bench.
"Cat Noir had to fight a villain. Let's hurry, we found Adrien before he ran into the villain."
"OK. "
The scene changes for the Agreste mansion. Santa Claus drops off Adrien at his home.
"Thank you very much, Santa Claus."
"You're welcome. Have a happy holiday season with your loved ones."
When he was going to leave. Ladybug appears and uses her yoyo to tie up the gentleman.
"Adrien, take shelter. This man is akumatized!"
"What?!"
"It's the worst Christmas I have ever had!"
In his lair, Hawk Moth feels the man's wrath.
"Ladybug, you just gave me my present in advance. Fly away little Akuma, go blacken this man's heart!"
The black butterfly flies out the window and joins the man outside, absorbed by his Christmas hat.
Man becomes Santa Claw. He transformed into an evil version of Santa Claus and his reindeer became monstrous.
"Merry Worst Christmas to everyone!" He flies away on his sleigh.
"Oh no. Adrien is going to your place quickly. Me and Ace of Kings are going to stop him. Cat Noir, Hawk Moth to release another villain." She informs her two sidekicks and sets off in pursuit of Santa Claw.
Santa Claw begins to spoil Christmas for the people of Royal Wood.
He stops at the town mayor's house with his niece.
"Merry Christmas Emma."
"Thanks, aunty."
Santa Claw arrives through the wall.
"? I'm Santa Claw, the meanest villain. I wish you a worse Christmas and I give you a good fear"
He throws a gift package in the air, which opens and leaves millions of spiders in the house.
The mayor and Emma are scared.
Santa Claw does the same in each of the houses and scares the families.
The three heroes of Royal Wood take action to stop Santa Claw.
"Any idea how to catch this Santa Claus?"
"..." She thinks.
"I have an idea." Ace of Kings said.
"What's this ?"
"Does Santa Claus love so much and he can't resist?"
"Biscuit? Give gifts?"
"Right. Ladybug we'll need your Lucky Charm."
The ladybug girl uses her Lucky Charm which makes a cardboard box appear.
Ladybug understood his plan. They wait for Santa Claw to set a trap for him.
Santa Claw flies over the town of Royal Wood. He sees Cat Noir with a gift package.
"?Santa Claw you won. We give you our miraculous. We have no chance against you." Cat Noir to the music of Night Club.
"A gift for me?"
{No ! It's a trap! just watch out!}
Evil Santa Claus ignores Hawk Moth's warnings and walks over to the gift package.
Ladybug appears out of the gift box and tears off the Santa hat. Ace of King tears it up.
The black butterfly has come out and is captured by Ladybug.
"Miraculous Ladybug!"
Millions of ladybugs repair all damage caused by Santa Claw.
"What's going on? Why am I here?"
After it's events. The Mayor of Royal Wood is having a big celebration. Everyone came.
Adrien is there too and celebrating with his class friends.
