Ariella is a 1980 Brazilian erotic drama directed by John Herbert and starring Nicole Puzzi, in which Ariella — a beautiful and lonely young woman from an upper-class family — feels like a complete stranger in her own home, starved of love and affection by her cold mother Helena, her father Rodrigo, and her two brothers Clécio and Alfonso, who secretly covet her sexually. When Ariella overhears a devastating conversation revealing that Rodrigo lured and ruined her biological father and raised her as his own daughter to steal his fortune, she decides to take revenge — using her own body as a weapon, seducing the men in the family one by one in an explicit erotic game of vengeance that dismantles the entire corrupt household from within.
