While visiting her dying mother in New Zealand, Detective Robin Griffin begins investigating the disappearance of Tui Mitcham, a twelve-year-old pregnant girl from the small town of Laketop.
In a breathtaking but remote mountain town in South Island, New Zealand, a twelve year-old girl named Tui is discovered to be pregnant. Local police enlist help from Detective Robin Griffin, a child protection specialist who has recently returned to the area to care for her mother.
As Tui's disappearance remains unsolved, fear for her survival increases, while her father solicits help, Robin has a run-in with the girl's half-brother and a perverted local.
A violent indiscretion sees Robin thrown off the case but she cannot let go. Her passionate affair with Johnno, Tui's half-brother, intensifies and complicates.
Robin is back on the case, whilst Matt gathers troops to hunt his daughter down. Tui's friends trek deep into the mountains to celebrate her birthday, with tragic consequences.
