La mujer perfecta (1979)

Marcela used to be a successful film star. Her pictures earned her a reputation as sex goddess, although in truth, she is rather shy and sweet-natured. After marrying an overwhelmingly wealthy industrialist and becoming a mother, all Marcela wants is to be a happy suburban housewife, the perfect woman, the model wife. However, she is haunted by her past, harassed by former admirers and shocked by day-to-day violence. Driven to the brink by a cool husband, a needy and jealous child, mocking and moralizing in-laws and utter loneliness, Marcela is pushed over the edge and escapes into a hallucinatory world of her own, where she will never be touched by anything grim or ugly ever again.
