Alucarda

In 1850, Lucy Westenra gives birth to Alucarda in a derelict colonial palace. Lucy fears the devil will claim her daughter and asks a hunchbacked gypsy to take the infant to a nearby convent. As the palace is filled with a demonic voice, Lucy dies from complications of childbirth.

The gypsy flees with the infant and delivers Alucarda to a convent of Catholic nuns. Lucy dies soon after, leaving the child under the guardianship of the sisters. Alucarda begins her life within the cloister, under a shadowy fate.

Fifteen years later, Alucarda is a teen at the convent and quickly takes an interest in Justine, a new orphan. She proclaims Justine as her sister and seeks her friendship. Their bond hints at a darker pact to come.

While playing in the forest, Alucarda and Justine witness a funeral procession led by a band of gypsies. A hunchback gypsy offers to sell Alucarda an amulet, drawing the girls toward outside influences. The encounter deepens their connection to the occult.

The girls explore the abandoned palace and wander into a crypt. They unwittingly unseal Alucarda's mother's grave and are overwhelmed by a powerful supernatural force. This moment sears a shared, sinister fate into their relationship.

During Mass, Justine inexplicably faints, and Alucarda begins reciting names of demons. The hunchback gypsy appears, and the girls invoke Satan in a ritual, while Sister Angélica has a vision of their dark rite. The convent's façade of sanctity begins to crack.

Back at the convent, the nuns struggle to make the girls repent for their blasphemies. Alucarda even attempts to seduce Father Lázaro during confession. In response, the community punishes themselves with a brutal flogging to try to save them.

As Justine's illness deepens, the nuns decide to perform an exorcism and bind her to a cross while instruments are used on her flesh. The ritual leaves her bleeding and dying, horrifying all who witness it. Dr. Oszek arrives to inspect the scene and is horrified by the cruelty.

Dr. Oszek takes Alucarda with him to his home after the exorcism, fearing for her safety. He leaves Justine behind to die, while Daniela, his blind daughter, offers comfort to Alucarda. Oszek resolves to protect Alucarda from the convent's turmoil.

Oszek returns to the convent and learns that Justine's corpse has disappeared. Upstairs, Sister Germana is inexplicably burned alive; her body reanimates and is decapitated by Father Lázaro. These events shake Oszek's belief in science and drive him to fear for Daniela's safety.

Oszek is led to the abandoned crypt by the nuns, where Justine's body lies in a blood-filled coffin. Now a vampire, Justine attacks Sister Angélica, but Angélica prays to halt the horror. Oszek pours holy water on Justine, driving her into a fit, and she bites Angélica before disintegrating.

Alucarda arrives at the convent with Daniela and uses supernatural powers to destroy the building, with clergy burning in the grotto. She collapses, and her body sinks into the ground as Father Lázaro and Oszek look on in horror. The finale marks the triumph of darkness at the cost of the convent and its guardians.
