On September 28, 2025, the Usoltsev family—Sergey, Irina, and their five-year-old daughter, Arina, along with their dog—disappeared without a trace in the Eastern Sayan Mountains. They had gone on a marked hiking trail on a sunny day but never returned. How could a modern search system, helicopters, and hundreds of volunteers fail to find a single trace within a half-hour's walk of the tourist center? In this video, we explore all the possible explanations: from a tragic accident to a mysterious phone signal and theories of a deliberate escape.
