In 2003 Zoe Jacobs disappeared during her 21st birthday party. Many believe that Zoe ran away but others suspect she was murdered. When police officer Sam Kahlil discovers Zoe’s blue backpack, Detective James Cormack is called in to investigate.
Cormack invites Sam to examine the contents of Zoe’s backpack and probe her memory for clues. Re-examining CCTV footage from the night she disappeared, Cormack discovers Zoe actually drove to Xanadu, the rural property where Joseph was living.
The field of suspects narrows. Sean's computer reveals a history of despicable behaviour towards women, including the photos taken of Zoe without her consent.
