A young girl loses her mind when her long-absent father tries to separate her from her mother. During the attempted kidnapping, the father kills the mother, which traumatizes the girl. After her father is imprisoned, the girl is cared for by neighbors who are unable to prevent a wicked man named Karkow from kidnapping her and taking her to a remote location. The girl grows up with a mental disturbance and becomes an accomplished dancer. One day, she is seen by a doctor of fortune, Dr. Zevallos, who decides to cure her, despite Karkow's opposition. Dr. Zevallos manages to heal the girl, but a physical confrontation with Karkow ensues, similar to the one between her parents. The shock of the experience restores her sanity, and the dancer begins a new life.
