Using Phoebe’s social media accounts as a map, Katy retraces her sister’s steps, searching for any clues the police may have missed. Was Phoebe being followed?

Katy realizes that Beth might be her best --- and only --- chance of finding the truth, and the two women form an uneasy alliance to find out what really happened to Phoebe.
