In 2001, Detective Inspector Robbie Lewis arrested Graham Lawrie for the brutal murder of three police officers. The murders ceased; Lawrie was given a whole life sentence. During the trial, however, he was incarcerated in a secure psychiatric hospital. For Lewis it felt as if the nightmare was over. However thirteen years later, the prosecution's case is falling apart. The forensics that were used to convict Lawrie have come into question and an appeal is launched for him to walk free. Lewis is fearing the worst will happen but nothing can prepare him for the resurrection of the original murders.
