Where Is Anne Frank

Inside the Anne Frank House, the glass case over Anne's diaries shatters and ink drips from a fountain pen onto the pages. The words lift off and form Kitty, a 14-year-old girl who was Anne's imaginary friend. Kitty quickly realizes she is real yet invisible and intangible to the visitors around her.

Kitty realizes she is invisible to people inside the house and cannot be seen by tourists or staff. She can observe the visitors without being noticed, which makes her new reality both wondrous and isolating. The more she moves, the more she understands the barrier between her existence and the living world.

Two drunk men smash Anne's bedroom window with rocks after spotting Kitty turn on a light. The disturbance draws the police, forcing Kitty to flee the scene with Anne's diary clutched in her hands. She escapes into the streets, realizing the danger of her new reality.

Kitty attempts to file a missing person report at a police station, but the officers are bemused and skeptical about a diary producing a girl. The officers threaten to detain Kitty, so she slips away and encounters Peter, a boy she had seen near the diary yesterday. He becomes her reluctant ally in a city that doesn't believe her tale.

Kitty goes skating with Peter, learning that straying too far from the diary dissolves her into ink. The pair races around town, and Peter finally returns her to the Anne Frank House the next morning before dawn breaks. The diary's pull keeps her tethered to the past even as she hunts for a future.

Kitty spends the day resting, while Peter returns to check on her. The police seize him for disruption and question him about Kitty, doubting his account of a living diary companion. The uncertainty deepens Kitty's resolve to prove her reality.

At night, Peter explains how Kitty's powers work and what happens when she leaves the diary’s orbit. Kitty exits to meet him again, and their meeting attracts the attention of the authorities, forcing them to flee once more into the city’s shadows. The secret friendship grows amid pursuit.

The next morning Kitty trades one of Auguste van Daan's high-priced watches for modern clothes, then visits the 6th Montessori School's library to catch up on history. She pores over editions of Anne's diary to fill gaps in her memory and to understand the real fate of the family. This research sharpens her purpose to honor Anne’s memory.

Kitty reads several editions of Anne's diary and the librarian hands her Otto Frank's book to deepen her understanding. She attends a stage adaptation of Anne's story and loudly critiques misquotations, drawing public attention. After the performance, she escapes the gathering crowd and reunites with Peter at a nearby shelter.

At the refugees' shelter, Awa explains their plight and shows how her father plans to build a hot-air balloon as a potential escape. The idea gives Kitty a glimmer of practical hope amid fear and uncertainty. The moment marks a turning point toward action.

Kitty and Peter travel by train to Westerbork, Auschwitz, and Bergen-Belsen to retrace Anne and Margot's footsteps. Kitty reads Otto's memoir and watches Hanneli Goslar's recordings, which deepen her sorrow and resolve. The journey stitches together past and present in a painful synthesis.

Arriving at Anne and Margot's cenotaph in Bergen-Belsen, Kitty collapses in grief while Peter comforts her. He convinces her to return to Amsterdam rather than dwell in an extraneous shrine. The weight of history presses on them as they plan their next move.

Back at the shelter, the government schedules deportations for the refugees tomorrow, heightening the sense of urgency. Kitty takes action by spray-painting a hot-air balloon somewhere visible to the world, signaling their struggle and location. Her newfound resolve turns protest into a call for shelter and safety.

Kitty delivers an emotional speech to a gathered crowd, accusing the world of deifying Anne and mishandling her message. She threatens to burn Anne's diary unless the government agrees to shelter the refugees, a bold ultimatum that shifts the public conversation. The moment tests Kitty's courage and resolve.

Peter offers to take Kitty back to the Anne Frank House to live as an immortal, invisible spirit. She declines, choosing life with the living world and their love. Kitty hands the diary to Awa, shares one last kiss with Peter, and then dissolves into ink, dispersing with the wind as the world witnesses her final act.
