The White Walls

David is a 13-year-old boy living with his family in a modest home in Foz do Iguacu, Parana - Brazil. His father, a despicable alcoholic who finds pleasure in abusing his wife during his spare time, is found murdered one night outside a nightclub. After an investigation, the police conclude that all evidence points to a single suspect: the boy himself, David. The problem arises when David's mother is also murdered shortly afterward, and now both deaths are attributed to him. His father was worthless; but why would David kill his own mother?

The explanation comes from a medical report that identifies David as having serious mental disorders. Consequently, David is locked away in a psychiatric hospital. However, it's precisely there that he suspects he's being ensnared in a terrifying plot, something that could alter his entire life course. But what secret could be behind the deaths of the boy's parents?

Doubting his own sanity, David begins to investigate, but each discovery only raises more questions, and the young man is faced with a disturbing dilemma: to what extent can he believe in his own reality?
