Healers tells the story of a woman known as Dona Josefa who has been a health care worker, midwife, and community leader for over 50 years. Besides taking care of villagers, she can deeply affect people who cross her path, like filmmaker Gabi Veras—who had a dream of becoming a mother. After a promise made by Veras, the director returns to the Sertão—Brazil’s most neglected area—and discovers the world of herbal medicine. Healers shows that despite the lack of support from authorities in these remote areas, traditional medicines which combine prayer with the use of herbs are slowly making governments realize their power. Today, some communities in the region that have been served by these herbal-based treatments have shown themselves to have efficient, trustworthy, and economical systems of alternative medicine. Intrigued by such an effective way of promoting health, Veras takes the viewer on her personal journey, uncovering an unconventional world that exists and functions thanks to women like Dona Josefa.
