Fargo's Allison Tolman stars in this mystery-thriller drama as Jo Evans, a newly divorced police chief on Long Island's Peconic Bay who decides to take in a little girl, Piper, whom she finds at the scene of a mysterious plane crash. Though she finds it odd that Piper has no memory of what happened (or even who she is), the mystery surrounding the girl only continues to develop as Jo investigates the events leading up to the accident.
