Ep 1. Madeline's Halloween

Madeline season 3 episode 1, titled "Madeline's Halloween," follows the girls of the boarding school as they prepare for one of their favorite holidays. The episode begins with the girls setting up for their Halloween party, decorating the school's courtyard with pumpkins, spider webs, and spooky props. Madeline, ever the leader, assigns tasks to her classmates and oversees the party planning.

While the girls work on their decorations, Miss Clavel announces that a surprise guest will be joining the party - the mysterious magician Monsieur Incroyable. Madeline and her friends are thrilled at the news and can't wait to see the magician's tricks.

As the party gets underway, Monsieur Incroyable arrives in a flurry of smoke and mirrors and starts his performance. His first trick involves him making a dove appear out of thin air, which impresses the girls. However, things take a turn when Monsieur Incroyable's next trick goes wrong - he accidentally makes Madeline disappear!

The girls are panicked when they realize Madeline is nowhere to be found. They search the school and the surrounding area but can't find any trace of their friend. They start to worry that Monsieur Incroyable may have something to do with Madeline's disappearance.

In the meantime, Madeline finds herself in a strange and spooky world full of ghosts, ghouls, and other Halloween creatures. She meets a friendly ghost who tells her that she's in the Halloween realm and needs to find a way back to the real world.

Madeline sets out on a quest to find her way back home, encountering all sorts of spooky obstacles along the way. She must navigate through a haunted forest, cross a rickety bridge guarded by a giant spider, and make her way through a foggy graveyard. She also meets a group of friendly witches who help her on her journey.

Back at the school, the girls are getting more and more worried about Madeline's disappearance. Monsieur Incroyable tries to explain what went wrong with his trick, but the girls are skeptical. They start to investigate on their own, searching the magician's bag and discovering a strange device that they believe may have caused Madeline's disappearance.

Finally, Madeline manages to find her way back to the real world, but not before experiencing some scary moments in the Halloween realm. She emerges from a creepy portal just in time to see her friends come to her rescue. The girls confront Monsieur Incroyable and accuse him of having something to do with Madeline's disappearance.

In the end, Madeline and her friends realize that Monsieur Incroyable didn't mean any harm, and that his magic trick was just a mishap. They forgive him and continue their Halloween party, relieved that Madeline is safe. The episode ends with the girls dancing and laughing, enjoying the spookiest night of the year together.
