To escape an overprotective family and an abusive partner, a young lawyer accepts an assignment in the Amazonian border town of Cruzeiro do Sul. There, she meets Carla, a local prosecutor, and Marcos, the son of an indigenous woman, and learns about an epidemic of violence against women that seems beyond comprehension. What she finds in the jungle is not only relentless oppression, but a deep longing for answers to an unsolved crime from her past. Through the ritual use of ayahuasca, she meets a chorus of warrior women on a path of revenge and recovers the painful details of her mother's death.
