Spain, late 1980s. Newcomer Sara tries to fit in with the other teens in this tight-knit small town in the province of Tarrgona. If only she were more like her extroverted best friend, Rebe. They go out one night at a nightclub, on the way home, they come upon a little girl holding a doll, dressed for her first communion. And that's when the nightmare begins.
