It's me against you - The mystery of the spellbound school

Years earlier, the alliance between the Order of Fairies and the Order of Scientists fractures when a scientist steals a sacred artifact. Cherì warns her companions that "A magic object was stolen." latestnetflix.com's view is that Faced with the danger that the traitor could claim the remaining items and gain absolute control, the orders ban the use of magic powers and hide their relics.

In the present, an abandoned school reopens after forty years of neglect. Pongo oversees the reopening after completing renovations funded by an anonymous benefactor. Sofi and Lui arrive to celebrate with him, performing a musical routine in front of the students until the stern principal orders everyone into their classrooms.

Pongo explains that the benefactor who funded the restoration wants to meet Sofi and Lui. Though the pair initially decline and walk away, they turn back out of concern for Pongo, only to discover him slumped unconscious in the principal's office.

The principal reveals her actions, stating, "He drank the juice I gave him. Which happened to be poisoned." Her benefactor, Mister S, emerges alongside Perfidia. Mister S delivers an ultimatum to save Pongo before an hourglass runs out: "Give us the treasure and we'll give you the antidote. No treasure, no antidote."

Carrying a blank map provided by Mister S, Sofi and Lui search the hallway for a passageway. Lui knocks on a blank wall to ask for a sign, causing an invisible doorway to appear. Passing through the portal into the hidden fairy school, text materializes on their map: "Anyone who comes to help, will be given help. Anyone who comes to take, will be taken." Locker doors suddenly slam and rattle against them, while Mister S, Perfidia, and an armed escort push the sleeping Pongo into the portal behind them.

Following the map's directions toward the Flying Room, Sofi and Lui navigate an outdoor garden filled with hallucinogenic butterflies. The pollen induces vivid visions, causing Lui to hear dogs speaking and mistake Sofi for Mrs. Marisa before they pull themselves free of the garden.

Inside the inverted Flying Room, an illuminated book projects a greeting from Cherì: "I, Cherì, founder of the Order of Fairies and principal of this school, welcome you. If you're here, it's because you are magical and special. Chosen." She explains that four magical objects were split between the two orders to maintain balance. When the room begins rotating, Sofi and Lui reach the exit door.

Mister S and Perfidia trail behind with Pongo, who briefly awakens babbling before falling unconscious again. Entering the Spell Room, Sofi and Lui are confronted by walking iron knights. Sofi finds an instructional grimoire and recites a shrinking incantation: "Miniscule as a flea, smaller than a tadpole, may you become teeny-tiny."

The spell turns Lui into a mosquito, allowing him to fly inside a knight's visor to distract it. Sofi then casts a second charm, reading, "Help Lui against the secret force, give him a hand, of course!" The incantation enlarges Lui's hands, and he hurls jars of snail slime to disable the knights.

Meanwhile, Mister S boasts to the slumbering Pongo about his appetite for pure power. Sofi and Lui enter the ancestral hall, where frescoes illustrate the history of the four objects—a gem, an hourglass, a coin, and a ring, and describe Cherì being entrusted with the Gem of Everlasting Life.

Living roots suddenly erupt from the floor, pulling Sofi downward through the floorboards before catching Lui as well. Underground, Lui finds Sofi transformed into fairy attire, holding the glowing Gem of Everlasting Life that the roots uncovered for her.

Mister S and Perfidia confront the pair, bringing Pongo along. Mister S discloses his past membership in the Order of Scientists and displays a magic ring on his hand, telling Sofi he took it "From your mom, to be exact." Using telekinesis granted by the ring, Mister S levitates Pongo over a drop to force a trade.

To spare Pongo's life, Sofi hands over the gem. Once the container is secured, Mister S refuses to provide a cure, mocking them with "There is no antidote. Adorable suckers!" Sofi taps into her innate magic to unleash a burst of energy from her chest, repelling the villains and driving them to flee with the gem.

Pongo awakens completely unharmed. Cherì's spirit cautions Sofi to keep her powers concealed and safeguard the remaining items. Pongo is appointed the new school principal, while elsewhere Perfidia informs Mister S, "Sir, I have good news. We've located the third magic object. It'll be ours soon!"
