Federal Investigator Aaron Falk is on his way to a small town deep in Southern Australian wine country for the christening of an old friend's baby. But mystery follows him, even on vacation. This weekend marks the one-year anniversary of Kim Gillespie's disappearance. One year ago, at a busy town festival on a warm spring night, Kim safely tucked her sleeping baby into her stroller, then vanished into the crowd. No one has seen her since. When Kim's older daughter makes a plea for anyone with information about her missing mom to come forward, Falk and his old buddy Raco can't leave the case alone. What would make a mother abandon her child? What happened to Kim Gillespie?
