In their secluded farmhouse, a mother, formerly a surgeon in Portugal, teaches her daughter, Francisca, to understand anatomy and be unfazed by death. One afternoon, a mysterious visitor horrifyingly shatters the idyll of Francisca’s family life, deeply traumatizing the young girl, but also awakening some unique curiosities. Though she clings to her increasingly reticent father, Francisca’s loneliness and scarred nature converge years later when her longing to connect with the world around her takes on a distinctly dark form.
