1974 ·1h 33m · ★ 4.4 (24)

Lucita has been locked away in a convent by her family in order to keep her away from her lover, Esteban. The pair make plans to elope, but Esteban is accused of heresy before Lucita can escape. Hiding in the convent, Esteban discovers the horrifying depravity of the covent's abbess, Sister Incarnation. Can Esteban rescue his love from this madhouse before the inquisitor discovers what is going on and has everyone executed?

Why it matters

A lurid dive into 1970s nunsploitation that blends religious horror with sleazy, transgressive thrills.

  • Peak Eurocult sleaze meets gothic dread — Sister Incarnation is a grotesque villainess channeling the era’s obsession with corruption cloaked in piety.
  • Perfect for fans of abrasive, boundary-pushing horror and exploitation cinema who appreciate practical effects and shocking set pieces.
  • A snapshot of the 1970s subgenre that pushed censorship limits, mixing eroticism, blasphemy, and body horror in a convent setting.
  • Not for the faint-hearted or those seeking subtlety — it’s a wild, often uneven ride, but a fascinating artifact of horror’s fringe obsessions.
