Blue Watch gets new custard-coloured uniforms that look simply silly. At a big alarm at London Arena, the other watches laugh at them and Sicknote drives them off with a jet. Billy continues chasing Lauren and gets beaten up by her pimp, so he goes to stay with Skip to nurse his wounds. Carole spies on Jack and Nicky, while Marianne and Nick go out together. Jean and Sicknote visit Sandra to talk about the memorial. Pearce goes to a job interview for Sub Officer in Hampshire, still haunted by his memories of Hallam's death. When the next shift begins, Nick sends Billy home off-duty because of his bruised face. Recall asks for a longer holiday to go to Scotland and visit his family. Blue Watch is called to a huge blaze at a fun fair, where tents and stalls are on fire.
