Long thought to be just another cold case, the story of Sigrid, the girl found dead by the train tracks in 1976, continues to haunt the town she vanished from. In this atmospheric microshort, locals recount her eerie reappearances across time: silent on the platform, running familiar streets, staring through mirrors, and walking the forest with eyes that never blink. Told entirely through reflections, voiceovers, and fragmented memories, Case File 11 blurs the line between warning and obsession. Sigrid isn’t just haunting them, she’s searching for someone.
