Chrissy is a 36-year-old ex-solicitor with three kids, a second hand Volvo and a husband who spends most of his time at high-powered meetings in Europe.

Jo, 29, is an ex-Major Crime Squad detective on the rise. Since the birth of her two-year-old son and subsequent unravelling of her marriage to another detective, she now works part-time in Police Intelligence and is bored to tears.

But when a young local mother with a shady past vanishes in mysterious circumstances, Chrissy and Jo form an unlikely partnership and ramp up their dormant job-skills to become a formidable pair of sleuths, exposing a simmering hotbed of drug-deals and violent murder in the suburbs.
