Dr James Ford is a Psychiatric Registrar in a North Yorkshire hospital. His personal life is a mess, and his colleagues might find him arrogant, but he appears committed to his vulnerable patients. So when he finds himself torn between a new mother attending a routine postnatal check-up and the sectioning of a floridly psychotic woman during a busy on-call shift, no one could predict the terrible consequences.

Dr Lucinda Edwards is a smart, battle-hardened doctor, but we meet her on a nightmare shift that ends in the death of an opioid overdose victim, Edith Owusu. Despite the support of her medical supervisor, Dr Leo Harris, Edith’s grieving father Sir Anthony Owusu, demands an enquiry into Lucinda’s actions on the fateful night.
