Cadenas de amargura (1991)

Evangelina Vizcaino (Bracho) is a resentful, traumatized woman with borderline personality who will do anything -including murder- to drag everyone near her to the chains of bitterness that she carries on a symbolic collar that is the key to deciphering the story. This is the most successful soap opera from Mexico after Cuna de Lobos and is more thriller and tragic than any melodrama.
