Part One - Night Games: Liz Rawton, now an Acting DI with the OCG, arrives at the station to head up an operation into catching a dangerous rapist who has been murdering prostitutes. Meanwhile, Ackland is unable to attend the final of the "Ask a Policeman" quiz hosted by Tony Blackburn, forcing Monroe to replace her with Spears. Spears saves the day and wins the relief a weekend away at a grand hotel. However, unwilling to go, she asks to be seconded to Rawton's investigation, but her request is denied by Cullen. Rickman and Clarke take a shine to local DS Pete Cork, but he only has eyes for a certain DC. By bribing a hotel rep, Cork ensures that his blind date for the salsa evening is Spears.
