Luis Bunuel directs this early 1960s melodrama starring Rosita Quintana as Susana, a mentally unstable woman who uses her sexuality to manipulate and get the attention she craves. After escaping from a reformatory for delinquent girls, Susana finds shelter in the farmhouse home of a peaceful and contented family. But she gradually uses her powers of seduction to undermine the stability of the family and wreak emotional discord, pitting the men against one another and causing the women to despise her.
