Based on the infamous real-life Schoklender case of 1981, the film portrays the toxic, claustrophobic atmosphere within a wealthy upper-class Buenos Aires family. Behind the respected public facade of businessman Bernardo Fogelman (Federico Luppi) and his wife Susana (Alicia Bruzzo) lies a household governed by psychological abuse, physical violence, and hidden depravities. As secret infidelities, suppressed sexuality, and domestic tyranny reach a breaking point, the couple's two sons are driven to orchestrate a gruesome crime, culminating in the murder of their parents.
