Dark Habits (1984)

Synopsis
In this Pedro Almodóvar film, a singer at a low-end nightclub hides out at a convent after her lover dies of a bad dose of drugs, and she meets a group of off-the-wall nuns while in hiding. The nuns range from one who writes sensationalist pulp fiction under a pseudonym to another who takes drugs, and another hooked on masochism. But their private lives and perverse foibles may be in jeopardy when a new mother superior arrives to take charge of the convent. ~ Eleanor Mannikka, All Movie Guide
