The detective series "Trap for Cinderella," based on the novel by Elena Mikhalkova, tells the story of a mysterious murder that shakes a suburban sanatorium. Detectives Babkin and Ilyushin set off on a long-awaited vacation, but they don't get a chance to relax. On the very first day, one of the animators of the boarding house is found dead in the forest. What's more, the victim's hair is cut short like a boy's, and candles and live flowers are placed around her body. It turns out that a similar crime had already occurred here twenty years ago.
