MyAnna Buring takes the role of DI Helen Weeks in this adaption of crime novels by Mark Billingham.
Pregnant detective Weeks has returned to a small town in rural Derbyshire, where two girls have suddenly been abducted. One of the reasons for her return is because the man arrested for the crime is married to a childhood friend of hers.
