When Rachel wakes up in a strange room, the morning after a neighbours party, she has no memory of what happened the night before. Why did her husband leave her alone at the party? Did they row? Why are Rachels arms so bruised? And why are her neighbours and friends so vague about what really happened? Little by little, Rachel pieces together the devastating events that took place in a friends house, at a party where she should have been safe. Everyone remembers what happened that night differently, and everyone has something to hide. But someone knows the truth about what happened to Rachel. And shes determined to find them.
