A mask in a display case, a grandfather who thinks he recognises it, and a theft that makes him a suspect: Nancy Mac Granaky-Quaye’s ‘Das Geheimnis der gestohlenen Maske’ (The Mystery of the Stolen Mask) begins with a crime to solve. Behind it lies a larger question: what does it mean when an object said to have been removed from a community during the colonial era appears in a museum as an exhibit?
The family film opens in cinemas across Germany on 29 October. Its central character, Johanna, is eleven and is just getting to know her grandfather Kito, who comes to Leipzig from Tanzania. During a museum visit together, Kito discovers a mask that he identifies as coming from his home village and believes to have been looted. Shortly afterwards, it disappears. Kito falls under suspicion; Johanna begins investigating with her friends Sweta and Anton.
A criminal investigation as a way in
The premise initially promises young audiences a familiar narrative: there is a suspect, three children conducting their own inquiries, and a mystery whose clues lead into the past. According to the film’s publicity materials, Muiné Keune, Greta Kasalo and Morris Mayer play Johanna, Sweta and Anton; Kito is played by Komi Mizrajim Togbonou. The screenplay is by Anna Maria Praßler and Eva Lezzi, with cinematography by Namche Okon.
A mystery can make historical questions tangible without reducing them to a history lesson. Yet this also presents a challenge: an investigation usually seeks a clear-cut solution and a culprit. The debate over colonial collections is more complicated. It concerns provenance, the circumstances of acquisition, institutional responsibility and the question of who has the right to decide what happens to an object. The film places these tensions within a family story in which Johanna not only investigates a suspicion but also re-examines her relationship with Kito and her own origins.
The display case is not a neutral space
The fact that Leipzig’s GRASSI Museum of Ethnology itself becomes a setting makes the institution part of the story. A museum preserves objects and places them in context; yet that framework did not emerge outside history. In the film, Kito’s claim sits alongside the museum’s claim to ownership — and Johanna’s personal loyalty. For children, an abstract conflict is thus rooted in a concrete relationship.
The mask belongs to the Makonde, according to the synopsis. The available information offers no further insight into the origins of the specific object featured in the film. This limitation is important: the plot centres on Kito’s conviction, not on independently verified evidence of provenance. The film thus begins by telling the story of how a historical claim changes the present and a family.
Suspense without spoilers
Mac Granaky-Quaye directs from a screenplay by Praßler and Lezzi; before its cinema release, there is only limited scope to assess how the film brings its story to the screen. The premise is known: Johanna, Sweta and Anton follow the trail of the missing object as past and present become intertwined. The resolution remains undisclosed.
What is interesting is the attempt to keep a politically charged debate connected to a child’s perspective. Johanna cannot follow the dispute over the mask as a detached observer: Kito is her grandfather, and his suspicion also affects her trust in the adults and institutions of her city. Whether the adventure framework can accommodate the historical conflict in all its complexity will become clear in the film. The question of who owns a returned or looted object is, in any case, more than a puzzle for young detectives.
