Plot
In 19th-century Macedonia, Maria – a "Wolf-Eateress", or witch, with a horrible burned appearance – enters the home of a newborn baby girl. The child's terrified mother says that if Maria spares the girl's life, she will give her up once the girl is 16. Maria agrees, but robs the girl of her voice before leaving. The mother hides her daughter, Nevena, in a cave, and raises her there with no knowledge of the outside world.
On Nevena's 16th birthday Maria arrives in the form of an eagle; the mother chases the bird out of sight, where Maria kills her and takes her form before taking Nevena out of the cave. A witch can use a spell, only once in their entire lifetime, to make someone else a witch; Maria does so by killing a donkey, scratching Nevena's chest and spitting the donkey's blood onto her before burning her wound with fire. Now a witch, Nevena gains deadly retractable black talons on her fingers and palm. Maria then pulls Nevena's mother's guts from a hole in her chest, causing her to resume her previous, burned form.
Maria tries to teach Nevena to catch, kill, and eat animals, whose blood witches consume for power, and warns Nevena that humans will hurt her; but the younger witch refuses to feed, preferring to play with the creatures, which angers an abusive and disappointed Maria, who eventually abandons her to fend for herself. Nevena spies on Maria assuming the form of a wolf by putting its entrails into a cavity in her chest, understanding how to shapeshift as a witch. Now on her own, Nevena comes across a village, and accidentally kills a young mother, Bosilka, before using her entrails to take Bosilka's appearance and assume her life. While Nevena's muteness and clueless attitude causes Humans to think Bosilka has gone mad, she slowly learns how to live as a human: how to cook and wash, how to communicate non-verbally, and the differences in how men and women treat her. All the while, Maria watches from afar. One night, Boslika's abusive husband tries to have sex with her. The unfamiliarity of the process, along with the rough nature of her husband, causes her to panic and kill him. She removes Bosilka's entrails from her chest cavity, reverts to her old self and flees.
She assumes the shape of a dog and comes across a group of young men, luring one of them away, Boris, before killing him and assuming his shape. Now a male, Nevena learns to plow the fields and thresh in Boris' village, but still acts in a confused and childlike way. His peculiar behaviour attracts the attention of the women of the village, who believe him possessed and attempt an exorcism, which they believe is successful, but say that the Wolf-Eateress that bewitched him will one day come back and spirit him away. Again, Maria appears and warns Nevena that growing close to Humans won't end well.
Nevena persists and enjoys his life in the village, even having a pleasurable sexual experience with a local woman. Upon discovering the body of a dying child, Biliana, who has fallen from a cliff, Nevana, crying for the first time and learning grief, assumes the form of the little girl and re-integrates Boris' village, where she is treated like a child for the first time. As time passes, she grows close to a boy, Yovan, who is seemingly also mute. One night she and the other children are told how, according to local legend, Maria came to be a witch:
Centuries ago, "Old Maid Maria", ageing and unmarried, led an unfulfilling, repetitive life caring for her elderly father. One day she happened across a witch and begged her for a husband and child. The witch clawed her chest and spat blood in her face – the first two steps of creating a witch – before walking away. Later, Maria was approached by a man who offers his son's hand in marriage. She accepted, but upon arriving in his home discovered that the son was dying; she is tied up by the villagers and raped by the dying son, because his mother didn't want him to die without having spread his seed. Left sick and ill after the death of the son, a desperate Maria attempted to drink a cow's blood to give her strength but was discovered and burned as a witch. The fire completed the witch's spell and transformed Maria into a witch herself – but only after her body had been left irremediably burned and scarred.
For Nevena, many years pass, and having grown into an older Biliana, marries the boy from her youth. Truly in love, she reveals her witch's talons, but he is not afraid. She becomes pregnant, but tragedy strikes when her husband is killed by a boar – implied to be Maria in disguise. Nevena gives birth to a baby girl, but is terrified that Maria might come to harm her. Her fears come true one morning when she finds Maria with her baby; Maria ridicules the child before cutting the baby's throat with her talon, but Nevana immediately uses her one witch spell and performs the ritual to turn her daughter into a witch and save her life. Astonished by Nevena's love for her child, a crying Maria finally admits her jealousy for Nevena's ability to act and feel like a Human. Nevena sets the child down and kills Maria; as Maria dies, Nevena remembers all the lives she has led.
