Plot
Click here to see spoilers for an unaired episode plot. In Miss Bustier's classroom, Mylène and Adrien are holding water guns, hiding behind the teacher's desk. They are acting as Agent Smith (Mylène) and Inspector Jones (Adrien) for a short film that Nino is making to enter in a contest held by the mayor. However, they cannot get past the first scene as Mylène is terrified of the monster's costume Ivan wears.

To calm herself, Mylène sings a lullaby about a smelly wolf, but she backs up into Adrien--who is having his makeup done by Juleka--and screams again. Chloé then makes fun of Mylène, making her run away. Adrien calls Chloé out on how mean she is, but Chloé dismisses it. Ivan runs after Mylène, trying to convince her to come back. He gives her a pin of his favorite band, the Zombies of Death. Mylène puts this pin on her hat, grateful to Ivan, but still upset. She runs away to the bathroom, crying.

Hawk Moth, sensing Mylène's distress, sends an akuma after her.

Back in the classroom, Nino rants to the class about not having Mylène. Chloé then states that Mylène was a horrible actress and that she could do better. This results in Ivan and Chloé arguing over Mylène's role in the film. As the producer, Marinette decides to go find Mylène. Until Mylène returns, however, someone has to fill her role. Chloé wants to fill it in only because there is a scene where Agent Smith kisses Inspector Jones. This causes both Marinette and Alya to freak out, Marinette because it could lead to her losing Adrien, and Alya because she, as the scriptwriter, never put a kissing scene in the script. Alya and Nino fight over the addition after Nino reveals that he changed the script without Alya's consent. Marinette stops the fighting, telling the class that she would find Mylène.

Right before Marinette enters the bathroom, the akuma finds Mylène, embedding itself in her Zombies of Death pin. Hawk Moth then turns her into Horrificator, a creature that grows on fear. After her change, pink slime is left on the mirror. Horrificator hides in a stall as Marinette enters the bathroom, calling out Mylène's name. Walking into the room, Marinette spots pink slime covering the mirror. It comes off on her fingers as sticky goop. Alya then enters the bathroom, warning Marinette that the scene where Chloé kisses Adrien is in the process of being filmed. Luckily, Marinette and Alya return in time to stop the scene.

Everyone begins arguing over Mylène again. Then, Chloé has the idea of turning Agent Smith into a nurse, thus annoying everyone else in the room. Marinette takes this opportunity to trick Chloé into searching for a nurse's uniform, as they do not have one on hand. Chloé then leaves, taking Sabrina, Kim, and Max with her. With the dilemma of a missing Mylène, Marinette takes on the role of Agent Smith--only because Alya reminded her that she could kiss Adrien--but not wanting her first kiss with Adrien to be like this or to replace Mylène.

When she is about to kiss Adrien, Marinette becomes nervous. Adrien pulls her forward, and after speaking her lines, Marinette almost kisses Adrien. The kiss is interrupted by Chloé, who returned to the room when she realized Marinette was tricking her since Marinette never agrees with Chloé.

Suddenly, yelling comes from inside the school. The students run out into the courtyard only to find piles of pink slime and Kim's armband. Kim and Max were taken by the monster Horrificator, but no one knew that yet. Adrien runs back to the classroom, claiming that he left a jacket that Inspector Jones should wear in the next scene. While in the room, he takes off a shoe to make the others believe he was captured, calls out Plagg, and transforms into Cat Noir. The other students decide to go to Principal Damocles' office. Once they get there, Marinette drops her phone in the hallway, rushing to the library where she calls out Tikki and becomes Ladybug. During this, Horrificator is covering the school in pink slime.

Inside the office, the students only find pink slime, with Mr. Damocles missing. When the students realize the school is covered in pink goo, Ladybug arrives on the scene. She tries to evacuate them, but Cat Noir arrives and claims that there are no exits. He then pulls Ladybug aside, reiterating the situation and what they have to do, the two in complete agreement. Nino takes this opportunity to film them.

Meanwhile, Horrificator, holding Max by its tail, deposits him in a slime pod. With Max terrified, Horrificator grows in size.

Chloé believes it's a good idea to break away from the group and hide with Sabrina. She believes that the two of them would draw less attention than in a group.

The students follow Cat Noir and Ladybug back to the original classroom, Ladybug spotting Adrien's shoe on the floor. Then, Nathanaël is captured by Horrificator, who was hiding under the desk. The students scream, fleeing the room, all except for Juleka, Nino, Ladybug, and Cat Noir. Horrificator growls at Juleka, but Juleka's response is that of awe, finding Horrificator to be cool. This causes Horrificator to shrink. Ladybug pulls Juleka from the room before she can be captured, Cat Noir distracting Horrificator to do so. Neither hero knows where the akuma is.

Escaping slime being barfed on them, Ladybug and Cat Noir bring the fight to the courtyard, the students hiding near another classroom. Their screams cause Horrificator to grow, and Ladybug notices it. She explains it to Cat Noir before rushing at Horrificator, her yo-yo acting like a shield. Ladybug hooks her yo-yo around Horrificator's arm, bracing herself against a lamppost. Cat Noir jumps down at Horrificator, baton raised, but is pushed back by a spray of slime, cementing him to the upstairs railing. Horrificator pulls on the yo-yo string, flinging Ladybug into a basketball hoop, cementing her there with slime as well. Satisfied they won't be moving, Horrificator approaches the students until she notices at Ivan. After staring at him, she licks him as she takes Alix as her next victim and escapes into a nearby classroom.

Cat Noir breaks Ladybug out of the basketball hoop, expanding his baton to break the board behind her head. On the ground and free, she wraps her yo-yo around his baton, tugging him off the second floor. They try following Horrificator, but the inside door is covered in slime and they can't open it. Ladybug realizes that Horrificator is Mylène, based on the fact she left Ivan alone. The group then realizes that Sabrina and Chloé are missing, but Ladybug isn't too concerned.

Chloé and Sabrina are in the science classroom, barricading the doors with lockers. Chloé is painting her nails and speaking with Sabrina about Ladybug when she notices that Sabrina is captured by Horrificator. Chloé screams, alerting Ladybug and Cat Noir to where she is. Ladybug and Cat Noir use the slime left behind to track Horrificator to the maintenance area. They bring the students with them.

Inside, pink slime drips in large globs from the ceiling and large pods rise from the floor. Ladybug calls out, asking if anyone was there. Chloé responds first, still painting her nails. Ladybug begins calling out other names, getting responses until she calls out Adrien's. She calls out his name twice, causing Cat Noir to hide behind some of the pods, pretending he is trapped to let her know he was there. After reassuring Ladybug, he asks if she found Marinette, and she responds that Marinette and everyone else was there. They try breaking open the pods, but it does not work.

Horrificator enters, spraying slime on the students and dramatically dropping down from a platform, landing near Ladybug. Cat Noir picks up slime pellets, throwing them at Horrificator to distract her. Marinette uses Lucky Charm, getting guitar strings as a result, which causes her to remember Mylène's lullaby. Off to her right, she spots a cart with random supplies on it, causing ten lights to flash in her lucky vision. She pulls the cart toward the students, stopping it before it can crash into Ivan. As Ladybug hands out the supplies, Cat Noir makes Horrificator follow him. Blocking another bout of slime and climbing a ladder up to a second-story platform, Cat Noir uses Cataclysm on the steel poles holding the platform to fall and trap Horrificator in a cone-shaped prison.

Jumping down from the platform, Cat Noir joins the students in their makeshift band. Rose is holding two trashcan lids as cymbals. Alya and Nino hold traffic cones as microphones. Ivan has a brush and dustpan. Juleka is holding a box with a lid. Cat Noir uses old water containers and trashcans as a drum set. Ladybug uses an upside down bucket, a broom, and guitar strings to form a bass. She then asks the others if they knew Mylène's lullaby, getting confirmation from everyone.

Ladybug begins the song, everyone else joining in on the second verse. The song causes Horrificator to shrink into a very small Horrificator. She runs to Ivan, jumping into his arms. Ladybug spots the pin on Horrificator's head, taking it off and crushing it between her thumb and index finger. This releases the akuma. Ladybug then captures it, purifying it. Throwing the guitar strings in the air, she shouts, "Miraculous Ladybug!" This cleanses the area inside the maintenance area and the rest of the school, freeing the students. Nino remains filming as Mylène returns to normal.

Hawk Moth, defeated again, claims he will destroy Ladybug as the window closes.

Nino films Mylène and Ivan kissing, marking the ending of his movie. He shows it to Mr. Bourgeois, the mayor, but the video is rejected from the contest due to the monster not being realistic enough. Adrien reassures Nino that this wouldn't mean the end of his career, as there are other directors who began from nothing. Alya offhandedly refers to the kiss not being the one they expected and Marinette smiles, gazing off into the distance as the endcard appears.
