Preoccupied with her 'best friend' Polly's arrest, PC Cathy Bradford visits Polly's boyfriend Max, implying to him that he may have been her next victim. Bradford ignores the urgent calls of domestic violence victim Paula Robinson and her son as the woman is brutally beaten by her husband. The woman's young son volunteers to act as bait for the father when he eludes the police, and DS Ramani De Costa begins to have serious doubts about Bradford. PC Gary Best is horrified that he knocked back PC Honey Harman the previous night, whilst DS Debbie McAllister and DC Juliet Becker argue after their night together. Polly Page is questioned at Barton Street by DCI Ross from MIT. Ignoring her solicitor's advice, she admits to assisting Owen Preston's suicide. To the shock of Polly and her colleagues, the CPS charges her with murder. Now working as a CAD Officer, Robbie Cryer realises that Bradford's deceit has been responsible for the assault on Paula, and threatens to tell all to Supt. Okaro. (thetvdb.com)
