When Rachel stumbles upon a body in the woods, she knows what she has to do: run. Get away. Do not be found at the scene. Last time, she didn't know and she ended up accused of murder. But when this victim is identified as her boyfriend's estranged wife, Rachel realises she's already the prime suspect. With mounting evidence against her, Rachel's only hope is to keep the truth about herself well hidden. Because 20 years ago she was someone else - Casey, a young nanny trying to make it as an actress in Los Angeles. When the family she worked for were brutally murdered, all the evidence pointed to her and she went to prison. Back then, she narrowly escaped the death penalty and managed to free herself on appeal. Now she's fighting to save the life she's spent years piecing back together. But with her behaviour raising suspicion and the police closing in, Rachel can't help wondering - was her discovery in the woods really just an awful coincidence or is someone framing her for murder? Someone who knows who she is and wants revenge.
