Plot
The film begins during winter, as the twelve girls are shown walking outside "at half-past nine in two straight lines". Before they head out on their daily outing, they soon find out that their teacher Miss Clavel is sick with a bad cold and is told by Dr. Cohn to stay in bed until she gets better, he then tells the girls to give her warmth and love while she recovers. Suddenly the girls are interrupted by Pepito who was playing his violin from next-door, he promises Madeline that he'll stop playing until Miss Clavel feels better again. That night as they're getting ready for bed, the children begin to reminisce about the good times that they've had with each of their families back at home especially the times when they have been sick as well. Madeline also tells her friends about the good times that she's had with her own family; she also shows them a special gold necklace with animal printings on them that her mother had given her, unfortunately since both of parents died many years ago she has no other family members to return to. Saddened by Madeline's story, the girls begin to feel sorry for her and they start crying but are soon comforted by Miss Clavel, who was awoken by the commotion. She reminds each of the girls that they all love and look out for each other, and that they are all are just as much a family as anybody else, bringing peace of mind to all of the girls.

One day, Madeline receives a mysterious letter in the mail from her from her long-lost Uncle Horst (Jason Alexander) from Vienna, who is planning on a visit. He arrives at the school later that week where is invited to have dinner with the girls including Lord Cucuface and Pepito's family, he then announces that he has been designated Madeline's new legal guardian (shows the court papers to Miss Clavel, her teacher). Horst plans on taking her to his hometown Vienna, to attend a fine finishing school, and plan on leaving the following day via the Orient Express. Madeline and her classmates react with shock, elation, and sadness. The children, wanting to prove that their school is just as good, puts on a musical to display their talents to Uncle Horst; however this does not impress him enough and he decides to take Madeline with him the next day.

That morning when Uncle Horst leaves with his niece the next morning, he takes Madeline on the Paris Métro, instead of the Orient Express, to an unfamiliar part of the town that ravaged with poverty and crime. Realizing that she is being kidnapped, Madeline throws beads of her mother's treasured necklace to make a trail to where she is taken to, however she keeps one of the beads which has a lion on it as a memento. It is then revealed that Uncle Horst is not Madeline's uncle nor is he related to her, but a Frenchman and a failed actor named Henri-(who can only do accents), who works for Madame LaCroque, the owner of a lace shop/factory. Henri takes Madeline to the lace shop's basement, which is full of kidnapped orphan girls who are forced into slave labor to making laces to sell. One of the girls, Fifi, befriends Madeline. It is then revealed that Madeline's court custody papers were forged by Madame LaCroque, and that the criminal duo plan to steal her family inheritance as she works in the factory.

Shortly after Madeline left, Miss Clavel, the girls, and Pepito tried to stop her and Horst so that Pepito could give her his Halloween parting gift: a shrunken head from Brazil. They arrive at the train station, only to learn that the two had taken the Métro, not the Orient Express. They also find Genevieve abandoned at the station. Fearing the worst, Miss Clavel enlists the police to help them rescue Madeline.

At the lace shop, the child workers endure enormous amounts of emotional and physical abuse at the hands of LaCroque; especially when Fifi accidentally causes her coughing to turn one of the laces yellow. As a result, LaCroque forbids Fifi from using white lace and instead allows her to make only black lace in the dark, which could potentially render her blind as explained by one of the girls whose grandmother lost her sight that way; Madeline defends Fifi and the other children in the process by explaining that Fifi is sick and that they each need more food and respect, however this gets her into more trouble. As punishment for talking back, LaCroque throws Madeline into a prison cell where she shown singing a song about love along with the other orphans. After breaking off a loose brick, Madeline tells Fifi and the children that they should escape from the factory; however Fifi said that she tried once but was caught in the process, and as a result LaCroque cut off her hair to make lace. She's then asked by Madeline why LaCroque is "so horrible", she explains through a flashback sequence of how LaCroque was once a famous cabaret dancer who experienced a performance disaster, by accidentally ripping her dress. In total humiliation, she stopped performing all together and sold all of her long blond hair to make lace. She and Henri then gained legal custody of all of the orphan girls. Rather than taking care of them (as she promised to the courts), they treat them as their miserable slaves.

Through following the trail of Madeline's necklace beads, Madeline's classmates along with Pepito and Genevieve find their way to the factory; back at the lace store, a customer tells LaCroque she wants red lace, which gives her the idea to cut Madeline's hair. Madeline tells her new friends that when an escape plan fails and that they may be small, but can follow as one. LaCroque interrupts their escape attempt and cuts off a few locks of Madeline's hair and prepares to torture her and the other orphans by deciding to give all of them haircuts. Back at the factory, Pepito uses his shrunken skull head to knock off LaCroque's wig from outside the window (revealing her bald head), and then frighten her to the ground. Meanwhile, Miss Clavel and the police catch Henri walking through the streets of Paris, planning to sell-off Madeline's belongings. Through a plea bargain deal, Henri agrees to lead them to the lace factory, in exchange for a lighter punishment. Madeline and all of her friends are able to tie up LaCroque in endless rolls of lace just as the police arrive with Henri and Miss Clavel. Henri makes one last attempt to escape, only to be tripped by Pepito's spool trick, allowing the girls to tangle him up as well. After the children celebrate their victory, the criminal duo are arrested and taken away by the police to be sent to prison and charged for their crimes; the girls give Madeline her mother's beads that they had found earlier. The factory girls, however, still have no family or a place to call home. During bedtime, Madeline's friends talk about what they would do with the reward money that they had received for LaCroque and Henri's capture. Danielle would go shopping for fashion, clothes and jewelry, Chloe would travel to exotic countries around the world, and Nicole would own a zoo "with all of her favorite animals". However Madeline has a better idea.

A while later Madeline-(who wearing her mother's now repaired necklace) uses the money to open up a special school for the orphans; she also reunites with Fifi who now has long hair and is completely healthy and fully recovered thanks to Dr. Cohn who had given her treatment. The girls from both sister schools rejoice in the fact that they are all one whole family. The film ends with Madeline smiling and winking at the audience.
