Traumatised by the loss of his daughter Claire, Taylor Bridges is self-exiled to Glorys Crossing, a small country town on the island of Tasmania. Taylor is the only ranger of an isolated National park ... a park that is drowning beneath the waters of the new dam project. Struggling with the guilt of Claire's disappearance, Taylor has since become a chronic sleepwalker. When another young girl goes missing, Taylor begins to question himself ... not knowing what happens when he sleepwalks. It's a race against time to not only find the missing girl, but redemption for a past better left lying at the bottom of the new lake.
