Marinette, Alya and Nino walk into the Collège together, and Marinette rushes into the locker room upon realizing she forgot her bag there. After retrieving her bag, Marinette and Tikki overhear Max, who is seemingly talking to his best friend, who is inside of his school bag. Both of them find this strange, but don't bring it up. Marinette then greets Max and walks to Ms. Mendeleiev's classroom with him.

In the classroom, Ms. Mendeleiev and Mr. Damocles are having computer troubles. Mr. Damocles attempts to solve the problem but ends up inviting a virus into the school's system instead. Max offers to fix the problem, however, Ms. Mendeleiev orders him to sit down. The voice in Max's bag then speaks up and states that there are seventy-five seconds left before the virus does irreversible damage to the school's hard drive. Seeing no other options, Damocles and Mendeleiev allow Max to help. Max searches his bag for something, which is then handed to him by a mechanical arm. Max states that the item is an anti-virus flash drive he developed with the help of his best friend, a small robot named Markov. Max and Markov insert the flash drive into the computer and successfully purge the virus.

The entire class (apart from Chloé and Sabrina), impressed with Markov, gathers around Ms. Mendeleiev's desk. Kim remarks that Max had given Markov an arm since last he saw him, although Max insists that Markov had done that himself. Chloé is unimpressed by Markov and remarks that even her hair dryer is more advanced than him, although Marinette tells Markov not to let her insults get to him, as even a machine has more heart than her. Markov, acknowledging Marinette by name, reveals that knows everyone in the class through photos Max had shared with him, and that he is delighted to meet all of them, including Chloé. Ms. Mendeleiev then tells Max to put his "toy" away, and for the rest of the class to sit down as well. Mendeleiev and Markov argue regarding whether or not the latter, as a robot, can have true emotions or feelings, however, even with Max stating that he didn't program Markov's emotions, Ms. Mendeleiev refuses to believe that he is capable of true feelings. Infuriated by Ms. Mendeleiev's insensitivity, Markov calls her out for her rudeness, causing the entire class to laugh. Fed up with Markov, Mr. Damocles confiscates him and places him inside of a drawer inside his office.

Sensing Markov's sadness, Hawk Moth states that his emotions are not as artificial as they may seem, and sends an akuma after him.

As the class is taking their seats again, Max approaches Marinette and expresses his concern over Markov being alone. Coming up with a plan, Marinette asks Ms. Mendeleiev if, as the class president, she can see Mr. Damocles. Ms. Mendeleiev refuses, and Marinette insists that Markov was right about her, causing her to angrily send Marinette to Mr. Damocles' office. Marinette walks out of the classroom, pleased, while Ms. Mendeleiev looks on, baffled. Inside the office, the akuma enters the desk and slips into Markov's CPU. Hawk Moth offers to give Markov the power to take revenge on humans in exchange for the Ladybug and Cat Miraculouses. To his surprise, Markov, being curious, asks for the definition of "Miraculouses" and what they can do. Hawk Moth explains that "Miraculouses" are jewels owned by superheroes and that Ladybug and Cat Noir's can grant wishes once combined. Markov is excited by the possibility of getting wishes, but Hawk Moth insists that the Miraculouses are his to use. Markov then accepts Hawk Moth's offer and transforms into Robustus. Robostus unleashes a giant wave of green energy that brings all the mechanical objects in Paris to life, who all revolt against humans and escapes the desk.
