In an American southern town, two girls disappear one after another. Soon they are found dead, with signs of violence on their bodies. The police are actively looking for the killer, but to no avail - even though the town is small and everyone here seems to be visible. Just at this time, a lot of troubles fall on the head of ten-year-old Sally O'Malley: her mother becomes seriously ill, her drinking stepfather has nothing to do with the family, they are going to be evicted from the house... In addition, Sally is sure that she knows the killer and that he has chosen his next victim exactly her. Of course, she is a big dreamer, and therefore they don’t really believe her when she says that a scary man in big black boots is hunting her. Sally understands: there is nowhere to expect support and she will have to protect herself and her younger sister, relying only on her own strength...
