Roger meets a young, pretty girl in the jungle, and she attacks him like an animal. Upon telling Tarzan and Jane, Tarzan explains she is Rimi the Lion girl, who he rescued years ago, and that she had returned to her lion family. Roger describes what are medical symptoms, so the three must entrap her to take her to her natural parents. She is not interested in civilized ways, nor her natural family. She wants to stay with her animal "parents." Tarzan must get her to understand, so she can be saved.
