The Libertine (La Matriarca; a.k.a. The Matriarch) is a 1969 Italian film directed by Pasquale Festa Campanile.
This is a sex comedy film about Mimi (Catherine Spaak), a young widow who discovers that her recently deceased husband kept a secret apartment for his kinky desires. Frustrated that he did not explore his sexual fantasies with his wife, she embarks on a quest to understand perversion and sexuality. She uses her late husband's apartment to seduce various men, each time learning more about the depths of human pleasure. Finally, lost to perversion and losing touch with her own identity, she meets the man who shares himself fully with her--accepting her for whomever she is.
