A woman sees her best friend murdered before her eyes, and thus becomes very traumatised. Her husband tells her to stay at home, where she discovers a little gris-gris bag. She opens the bag, without knowing its magical origin, and smells a powder. She begins investigating and discovers a strange address: "Academia #10". She then goes there and meets a witch, who warns her of the dangers of the powder she smelled and the dark powers of voodoo. She then meets a psychologist, who becomes interested in her case and the black magic surrounding her. When a mysterious black man appears and strange things begin to happen, her life turns into a race against time and against a powerful voodoo deity.—Marcos Villasenor

Dolores Berthier is a well-to-do housewife living with her husband, Andrés, in an elegant old building in latter-day Mexico City. After Eva, her neighbour and friend, is savagely murdered on her doorstep, Dolores freaks and starts to become delusional. Concerned, Andrés asks her to meet with a psychiatrist; meanwhile, at Eva's, she finds a book with the address of Madame Endor, a mysterious sorceress who seeks to aid her. Unknown to Dolores, she is entangled in a web of voodoo and black magic. As her kindly doctor tries to figure out what is going on and joins forces with Madame, who finds herself dying, Dolores's marriage starts to come apart at the seams because of certain shocking revelations of murder, treachery, and deceit, and an eerie zombie-like figure starts to stalk her luxurious apartment, seeking to settle an old score.—Miguel Cane <[email protected]>
