The search for Tui grows more intense; Questions multiply as Detective Robin Griffin's pursuit of a suspect escalates unexpectedly.After a tense encounter with pregnant girl Tui's father, Robin Griffin is driving home and confronts a disturbing sight: Tui's rider-less horse on the road. The hard-bitten Laketop community turns out in force to search for her but the questions only multiply. As the search grows in intensity, so do fears for her survival. Tui's father addresses a crowd assembled in the local pub asking anyone who knows anything to come forward, but his threatening words hardly seem to encourage hope. Robin pursues an accused pedophile to his house for questioning, but the encounter spirals quickly out of control. Desperate, Robin turns to Johnno Mitcham, the girl's half-brother, for help. His support may prove crucial to the case and to Robin's safety, but it also soon entangles Robin more deeply in a battle with her own past.
