Thirteen-year-old Marcielle lives on Marajó Island in the heart of the Amazon rainforest with her father, mother, and three siblings. Prompted by her mother’s words, she idolizes her older sister who supposedly escaped her reality by “finding a good man” on the barges that ply the region. As Tielle matures, her idealized visions shatter, leaving her trapped between two abusive environments. Increasingly worried about her younger sister and the bleak future they face, she decides to confront the oppressive system that controls her family and the women in their community.
