Fisherman Simon returns to his native village of Boka Sarantonio with his Colombian wife Adelaida after many years away. His absence has changed him so much that the villagers become convinced that Adelaida has brought a curse upon the village. To avert it, barmaid Rosoura enlists the help of brua, with fatal consequences.

During a protracted drought, Solem (Marian Rolle) uses her magical powers to protect her village from evil spirits. She also provides food, searching the wilderness for edible plants. During one foraging mission, she encounters an evil spirit who impregnates her. Solem's fellow villagers believe her power to be derived from her virginity, and when she gives birth they ostracize her. She then embarks on a quest to purify herself and restore balance to the world.
