Corazones en Tinieblas

Set in 1934, and meant to dramatize social injustices, this melodrama examines an official's attempt at land reform. The landowners are against any reform and are also not interested in ending the exploitation of their workers. On the opposite side of the fence, the Native Americans have almost no way to better their living conditions or to fight oppression. They are also plagued by "superstition," which leads to some misguided actions that only make things worse. Violence and sexual encounters are interspersed throughout the story.

A young girl's arrival at a convent after the death of her parents marks the beginning of a series of events that unleash an evil presence on the girl and her mysterious new friend, an enigmatic figure known as Alucarda. Demonic possession, Satan worship, and vampirism follows.

Entre tinieblas / Dark Habits - by Pedro Almodóvar (1984)

Yolanda sings in a seedy nightclub. When her boyfriend dies of an overdose, she fears the police and seeks refuge in a convent that saves women from the streets. These off-beat nuns include a heroin using abbess who loves Yolanda, one who writes romance novels under a pseudonym, another raising a tiger in the convent yard, and one who designs fabulous fashions and is in love with the local priest. They plan an evening extravaganza starring Yolanda to celebrate the abbess's birthday and to convince their wealthy patron not to abandon them.
