Series 1

After being disgraced, investigator Rose Linden is assigned under administrative manager Marion Maloney at the Criminal Justice Review Agency (CJRA). Despite being told to resume light duties only, Rose ignores orders and soon drags Maloney into a case of injustice, involving a mother's plea that her son is not guilty of the rape and murder of his daughter.

As the investigation deepens, Rose is forced to battle her own demons as she's forced to cope with the knowledge that she has recently freed a man who is actually guilty of the crime for which he was sentenced. Will this impair her judgement, or will Maloney manage to steer the investigation back on course?
