Stephanie is in the Outback of Australia recovering from the death of her partner when she receives news of the suicide of her best friend, Melissa. The realisation that Stephanie will never again be able to share her inner most thoughts and aspirations with Melissa, is devastating.

Back in Ireland, as she attempts to come to terms with her friend's death, Stephanie starts to look at inconsistencies in the story of Melissa's apparent suicide. Why would she do such a thing when she had so much to live for? And leave her young daughter without a mother? The Gardaí are too ready to accept a verdict of suicide, but Stephanie becomes convinced Melissa was murdered and is drawn into a search for her killer.

And as Stephanie intensifies her search for justice, gets ever closer to discovering the true reason for Melissa's death, that search turns into a fight for her own life.
