Plot
The episode starts with Gabriel standing in front of Emilie’s cryogenic pod in the repository. He says to her that he had done everything for her, and if necessary, he will do it hundred times over again. Then he gets a call from Nathalie telling him it’s time for the conference of the 100th collection of Gabriel brand, and he leaves the repository.

Outside the Agreste mansion, Bob Roth’s coin falls in a roadside sewer, and he becomes upset at the thought of losing money. As a result of Bob Roth’s negative emotion, the Butterfly Miraculous glows, alerting Gabriel just as the limo pulls up to the conference. He tells Adrien that he is not feeling well and Adrien will represent him instead. Adrien tries protesting, but Gabriel insists while twisting his ring. Adrien sadly obeys and is dropped off alone.

Moolak, the akumatized form of Bob Roth, converts people into coins and storing them in his safe. Shadow Moth reminds Moolak about the Ladybug and Cat Miraculouses, and if he will not obey him, he will take his powers back. Just then, Ryuko uses her lightning power on the safe but is unable to break it. It is shown that Ladybug, along with Ryuko, Pegasus, Vesperia, Pigella, Purple Tigress, King Monkey, Carapace, Viperion, and Polymouse are fighting against Moolak. Ryuko says that it is impossible to enter the safe without opening its door. Then, Ladybug tells Pegasus to use Voyage to get inside the safe. But, when he uses it, he is unable to get inside the safe due to the lack of space in the safe. Vesperia says that it must be cataclysmed to defeat him, but Ladybug replies that she had been sending Cat Noir messages but he isn’t picking up. During the conference, Adrien is watching everything unfold in the building while Nathalie coaches him through an earpiece when the battle above the building distracts him. Ladybug eventually gives up and uses her Lucky Charm which gives her a fire truck. Ladybug then ties up Moolak with her yo-yo while Polymouse distracts him by using Multitude. Vesperia who is then protected by Carapace’s Shell-ter allowing her to safely paralyze Moolak, with help of Venom. Viperion uses Second Chance and rewinds time every time he gets the safe password wrong. After 100 attempts, he cracks the code, takes out the akumatized coin and tosses it to Ladybug. Ladybug takes the coin and uses Miraculous Ladybug on it and repairs everything back to normal. Adrien watches the Miraculous Ladybug effect from the conference place and the heroes do their signature “Pound It” fist bump. Meanwhile, in Shadow Moth’s Lair, Shadow Moth vows to get their Miraculouses, even if it takes another 100 attempts.
