It starts at the Francois Dupont High School, Yvette is giving out fliers for a movie night at her house. "Movie night at my house, we're showing the movie called the Fantastic Beasts, and where to find them," she said to Alix. "Who's idea for a movie was it?" questioned Alix. "My 13-year-old sister, Macy" replied Yvette. "Fine, I'll go see it" Alix takes the flier. "Who wants to see The Fantastic Beasts?" Celina, Meena, Adrien, and Nino see Piper handing out fliers. "What's up with Piper?" questioned Nino. "She's handing out fliers to see the new J.K. Rowling film, the Fantastic Beasts" answered Celina. "Macy's dying to see it all month since it came out" added Meena. "How'd you know that your little sister wanted to see it?" said the curious Adrien. "Because she's a fan of J.K. Rowling," said Celina. "Of course" replied Adrien.
Yvette sees Marinette and Alya and she walked up to them. "Marinette and Alya, do you want to see J.K. Rowling's The Fantastic Beasts?" she said. "I've heard about it," said Alya. "Yeah, but it came out last month, last time Macy spoiled the movie for us," said Marinette. "I know, but my little sister felt really bad about what happened and she decided that Macy and I show you the fantastic beasts," said Yvette.
"Yeah, but what if Macy spoils it again?" questioned Marinette. "It's fine, plus, I'll be inviting Adrien," said Yvette. "Okay, I'm in!" Marinette takes Yvette's fliers and she gave the second one to Alya. It shows to Diego who showed up at the school. "Yo guys, what's going on?" said Diego. "Yvette's handing out fliers for the fantastic beasts," said Meena. "Oh, really?" replied Diego. "Yeah, my sister, Macy, is excited to see it all month," said Celina.
"Oh, I get it" added Diego. "Yeah, she's a huge J.K. Rowling fan" replied Celina. "What is she gonna do?" questioned Diego. "She's not gonna spoil the movie, like, last time," said Celina. "I guess I'll go," said Diego. "Okay" Celina turns to Yvette. "Hey, Yvette! We have someone who wants to watch the Fantastic Beasts!" she said to her sister. Yvette walked up to Diego. "Yes! Thank you" Yvette handed out the flier to Diego.
"That made Yvette really eager," said Adrien. "So what happened last time?" said the curious Diego. "Last time we did movie night, Macy spoiled the movie when she got too excited," said Celina. Then it shows to Celina's house and everyone is here. "Okay, movie fans, the movie will start in 10 minutes," said Yvette. "Hey, Celina, is Macy here?" questioned Marinette. "Yeah, I think so" replied Celina. Macy arrived. "Hey, guys! Are you excited to see the Fantastic Beasts?" she said. She realized something. "Oh, wait, I forgot my water bottle, I'll be right back" Macy went down to the basement. "Is this a really good movie?" Diego asked. "Yes, it's good, I've seen it before, and Macy is dying to see it," said Yvette. "It's true. But Zoe decided not to tell Macy" said Celina. Macy comes back from the basement with her water bottle.
As when the movie starts, the power somehow went out. "What happened?" questioned Macy. "The power went out," said Celina. "I don't know how'd that happened" added Macy. "Did you cause the power outage, Macy?" said Yvette. "Why would I do that?" questioned Macy.
"I remember last year, you were playing the electrical box when you're not supposed to," said Yvette. "I did not this time!" said Macy. "You know what. I'll call Meena's Dad, and fix the electrical box until it's fixed, we'll watch the movie without you" Yvette said to Macy. "W-What?!" said the upset Macy. "I'm not happy about this. Go to your room now!" said Yvette. "Your not the boss of me!" said the frustrated Macy when she runs out the front door.
Then, it shows to Hawk Moth's lair. "My, my, she really wanted to see that movie, but now she's in despair, in that case," said Hawk Moth. The Akuma landed on Hawk Moth's hand, and placed dark energy on it, the Akuma flew away. "Fly away, evil Akuma, and take control of that frustrated movie-goer!" said Hawk Moth as the Akuma is heading to Macy.
It shows Macy at the park, sitting on a swing. "I didn't even cause the power outage. Thanks a lot, Yvette!" she said to herself. The Akuma landed on Macy's sunglasses, Hawk Moth started communicating with her. "Hawk Moth is my name and Elektra is now yours. I'm giving you the power of electricity, but you will help me in return when the time is right" said Hawk Moth. "Yes, Hawk Moth" Macy gets off the swing and she changes. It shows to Celina's house. "Zoe, that was uncalled for," said Marinette. "I wasn't very happy about what happened. Macy shouldn't play with the electrical box this time" said Yvette. "What if she didn't?" questioned Diego. "Yeah, what if Macy's right? What if someone framed her?" questioned Celina. "I guess if you're right. But, now I feel all bad" said Yvette.
Then they heard screaming. They went outside and they see Chromo-Girl. "What is that?" questioned Yvette. "Bad news I'm sure," said Marinette. "YOU!" Elektra speeds up to Yvette. "You better think twice by not letting me see the movie!" she said. "What are you talking about?" questioned Yvette. "You know what I'm talking about," said Elektra. "Macy?" said Marinette when she figured it out. "Macy is gone, now I'm Elektra!" said Elektra. Marinette runs off.
Tikki gets out of Marinette's bag. "Hawk Moth must have released another Akuma," said Tikki. "Well, only one thing to do," said Marinette. Marinette's earrings turned red. "Tikki spots on!" Tikki gets absorbed into Marinette's earrings and the red earrings have five black dots on them, Marinette transforms into her superhero alter ego, Ladybug.
Adrien, Diego, and Celina saw what happened by watching them at the window. "I know a place we should be, follow me" Celina takes Adrien and Diego to an alleyway. "Is it really Macy?" said the curious Diego. "Yeah, it looks like we have to save my sister," said Celina. "Let's do it. We're a team, aren't we?" said Diego. Adrien, Diego, and Celina called their Kwamis. "Time to transform!" the trio said. "Plagg claws out!" Adrien's ring turns black, Plagg gets absorbed into the ring and a green paw print appeared on the ring, Adrien transforms into his superhero alter ego, Cat Noir.
Diego's pendant turns to gold. "Leo, let's roar!" Leo gets absorbed into the pendant and an orange lion paw print appeared, Diego transforms into his superhero alter ego, King Leone. Celina's gold piece of her hairpin turns pink. "Papilla, wings up!" Papilla gets absorbed into Celina's hairpin, a butterfly symbol appeared on Celina's hairpin, Celina transforms into her superhero alter ego, Butterfly.
Butterfly, Cat Noir, and King Leone head to fight Elektra, Ladybug uses her Yo-Yo on Elektra to make her fall over and she gets up and notices Ladybug. "So your Ladybug, I heard very pathetic things about you," she said. "Leave those people alone!" said Ladybug.
"Yeah right, Ladybug, since I have the power of electricity, I can do this" Elektra used her electricity power and caused a blackout in Paris. Cat Noir, Butterfly, and King Leone show up. "Macy, stop this right now!" said Butterfly. "I'm not the trouble-making Macy anymore, now I am the electrifying Elektra!" she introduced herself. "She's not listening to the reason," said King Leone. "Then let's not change that," said Cat Noir. They go on the attack Elektra, Cat Noir went out in the attack as he used his staff, then Chromo-Girl shocked Cat Noir with her electricity powers.
"It's not okay to play with electricity, Elektra," said Cat Noir. He falls over in pain. "Oh man, not cool!" King Leone takes out his buster sword. Butterfly got mad at Chromo-Girl and she took out her two fans. "How dare you electrocute my friend!" she said furiously as she and King Leone are attacking Chromo-Girl, King Leone attack Chromo-Girl with his sword. "Haven't you know? I can absorb electricity, with that, Paris will have a blackout" said Elektra. "Not if I could help it!" said Ladybug. Butterfly realized something. "Wait a minute, I bet the Akuma is in her sunglasses," she said. "Then we get a ride of them," said Cat Noir.
"Lucky Charm!" Ladybug used her Lucky Charm power, and the item was revealed to be rubber gloves. "Rubber gloves?" she questioned.
She spotted Elektra's sunglasses. "The glasses, of course!" said Ladybug. Ladybug puts on the rubber gloves and grabs Elektra, the supervillain tried to shock Ladybug but it didn't work. "What? I've should've shocked out by now!" said the frustrated Elektra.
"Rubber doesn't conduct electricity," said Ladybug. Ladybug kicked Elektra and grabbed her sunglasses and she breaks them, the Akuma is released. "No more evil-doing for you, little Akuma" She begins to capture the Akuma. "Time to de-evillize!" Ladybug captured the Akuma with her Yo-Yo. "Gotcha!" Ladybug releases the purified Akuma. "Bye-bye, little butterfly" Ladybug started to throw her rubber gloves up. "Miraculous Ladybug!" The Miraculous Ladybug repaired the damage caused by Chromo-Girl. Chromo-Girl turned back into Macy. "What I'm I doing here?" questioned Macy. Ladybug, Cat Noir, Butterfly, and King Leone gave each other a fist bump. "Pound it!" they said. Then it goes to Hawk Moth. "Not again! One day, Ladybug, I will destroy you!" said the furious Hawk Moth.
It goes back to Ladybug, her miraculous beeps. "Time to bug out, later!" said Ladybug. The others leave and change back. "See, I told you it was easier for us," said Diego. "Yeah, if only we knew who Ladybug is," said Adrien. "Don't you mean if you knew, lover boy?" said Celina when she teased Adrien. "Hey, not funny!" added Adrien. They go back to Macy. "Sorry about Yvette being upset with you, Macy," said Celina. "It's okay" replied Macy. The power goes back on. "Hey, the power's back on," said Macy. "Then let's go finish the movie," said Diego. They take Macy to Celina's house.
It shows to the gang, watching 'The Fantastic Beasts (and where to find them) and they finished the movie.
