The detectives reopen the 2006 case of a murdered Jane Doe when relatives and friends identify her as an Amish teenager who went missing in Philadelphia during her Rumspringa.
- A young Amish teenager visits the homicide unit in search of her missing sister, who disappeared during her rumspringa ("running around"), a cultural rite of passage that temporarily separates Amish adolescents from their sheltered communities and allows them to experience the "English" (non-Amish) lifestyle. When the detectives identify the missing girl as a savagely murdered "Jane Doe" found in 2006, solving the case becomes an unusually complicated and uncomfortable process. Key witnesses lie among both the Amish and the "English," and Detective Rush has to bring the two clashing cultures to a temporary reconciliation. As the story unfolds, it is clear that Rush's dilemma in many ways mirrors that of the young Amish victim, who was torn between her thirst to experience "English" life and all it had to offer and her deep love for her family and her safe, secure Amish world.
