The Witch’s Mirror

Sara consults the spirits through a magic mirror and learns Elena is in danger. The mirror reveals the identity of Elena's would-be killer and also shows a mysterious rival woman whose name remains unknown. Sara resolves to warn Elena and protect her from the coming threat.

Eduardo poisons a drink and brings it to Elena's bedroom, where she drinks it and falls. Sara pleads with the spirits to shield Elena, but a spectral voice commands her not to interfere. Elena dies that night, leaving the household in shock.

Elena's body is laid to rest in a cemetery, and Sara communicates with Elena's spirit from beyond. Elena's death sets Sara on a path of vengeance against those who harmed her goddaughter. The mood is haunted by the promise of revenge.

Some time later, Eduardo remarries and introduces Deborah to the household. Deborah explores the house and immediately feels an eerie chill, especially in Elena's former room. The new marriage initiates a fresh wave of unsettling phenomena.

Deborah is unsettled by the house, and strange events begin in Elena's former room, including drafts and odd sensations. The next day, Elena's tune on the piano unsettles Eduardo as he notices the room reacting to Deborah's presence. Deborah pushes for remodeling to erase Elena's memory.

Deborah discovers Elena's diary on the shelf, but it vanishes before she can show it to Eduardo. Mysterious activity continues as the fireplace dies and the piano seems to play Elena's tune on its own. The couple grows increasingly convinced that Elena's vengeful spirit haunts them.

Deborah glimpses Elena's figure in the bedroom mirror, which causes her to faint. Eduardo also witnesses Elena in the mirror. In a fit of fear, Eduardo shatters the mirror with a lantern, triggering a fire that severely burns Deborah.

With Gustavo's help, Eduardo begins reconstructive work, performing skin grafts on Deborah using cadaver tissue. The operation is grisly and morally fraught, driven by the obsession to replicate Elena and restore Deborah's appearance. The house becomes a makeshift laboratory balancing science and vengeance.

Eduardo decides to replace Deborah's burned hands with those of the recently deceased pianist. They exhale the pianist's coffin but discover she had been buried prematurely. In the lab, Eduardo sedates the pianist and amputates her hands for transplantation.

Sara orders Gustavo to consider turning himself in, while she burns the severed pianist hands in a furnace. Elena's disembodied hands take their place on Deborah as the procedure continues. Tension mounts as the supernatural presence enacts its revenge.

Eduardo transplant a pianist's hands onto Deborah, who then violently struggles and unintentionally plays Elena's tune while trying to strangle him. Deborah becomes aware of Sara's chants to the spirits and panics. They uncover the bodies Eduardo used for the procedures.

Authorities arrive after Gustavo signals them, and the room erupts in chaos as Deborah's hands fatally stab Eduardo. The transplanted hands attack Gustavo, then disintegrate, while Deborah's own form remains disfigured and Sara vanishes into the air. The house is left in eerie silence as vengeance is fulfilled.
