Horácio tells the story of a dysfunctional family, in which social norms no longer exist, and where relationships are basically guided by impulse. The head of the family is Horatio, an 80-year-old cigarette smuggler on the run, hiding in a surreal, baroque apartment with his daughter, Petula, and Milton, his favourite thug. While he keeps his daughter locked up in her bedroom, Horatio flirts with his goon, for whom he has had repressed feelings for years. However, Milton’s love for a mysterious woman, and Petula’s attempts to free herself with the help of a former lover, clash with Horatio’s tyrannical whims.
