Abode of Darkness

The action takes place in the abandoned Heilstetten sanatorium near Berlin. During Nazi Germany, inhumane experiments were conducted here on patients with tuberculosis. After the war, the building was closed, and since then, terrifying rumors have swirled around it—they say evil still rages within the sanatorium's walls, and paranormal activity has been reported in the surrounding area.
A group of young vloggers decide to test these rumors for views. Among them are Finn and Charlie, pranksters from their channel "Prankster TV," beauty blogger Betty, and their assistant Emma. They make a bet: who can survive in an ominous place for exactly 24 hours? To feel more confident, the guys bring equipment: night vision cameras, thermal imagers, extra batteries, and tripods. Theo, a medical student and part-time tour guide, helps them gain access to the sanatorium. Theo suggests the guys go to the sanatorium, but undercover, so as not to reveal themselves to anyone, otherwise they'll get in trouble. Soon, a girl named Marnie arrives on the scene. She's Theo's ex-girlfriend, and he wasn't happy to see her. She suffers from claustrophobia and runs her own blog. Theo didn't believe Marnie's performance on camera six months ago about her claustrophobia in the elevator test and they broke up due to personal reasons, but Marnie still has feelings for Theo, although it's hopeless
Having infiltrated the building, the bloggers initially treat the scene with irony, discussing urban legends on camera. But they soon begin to realize the rumors aren't so exaggerated: there really is something in the building. As they explore the gloomy corridors and rooms, signs emerge that they are not alone. Unexplained phenomena are captured on camera, and the heroes find themselves in a situation where the desire to make a cool video outweighs their instinct for self-preservation. They must decide: continue filming for views or try to escape a place that turns out to be far more dangerous than any internet horror story. It's late winter, no snow, but it's cold.
