Without permission and support from the school, a young teacher (Fernanda Vasconcellos) seeks to understand the strange behavior of Gustavo - a silent boy who is only 7 years old, nicknamed by the other children “Dead Volume”. However, the boy's parents (played by Julia Rabello and Daniel Infantini) claim that Gustavo's behavior at home is completely different from the one described by the teacher. The parents decide to conduct an investigation on their own, putting the teacher’s job at risk.
The young teacher tries to calm down the parents and prevent a scandal from spreading in school. Nevertheless she ends up increasing the distrust of the parents, turning her into the main suspect, and making the puzzle even more unsolvable.
The film is a good example that a good thriller can be done without many resources. The action takes place mainly in the classroom. Great screenwriting, acting, directing were enough to create a compelling story with several twists.
