Blue Watch face a race against time when two building workers are buried under collapsed scaffolding at the edge of a river. There is just half an hour before the incoming tide will drown the trapped men and Tate urgently requests a thermal imaging camera to help find them. But when ADO Scase arrives, he orders the rescue work to be halted until the remaining scaffolding has been secured. Tate ignores Scase and the men are dragged out just in time. Josie attends a Junior Officers Training course, the first woman to do so. Sicknote is jealous as his role as the leading light in POP's is unsure after the arrival of a newcomer, Dominic. Vaseline ends up sleeping with Marion one by mistake while Charisma tries to track down his long-lost father. He is sent to the Savoy Hotel, but is disappointed to find he is only a cleaner there. He tells the Watch that the old man died a hero's death in the war, but nobody believes him. Tate learns he has to go before the Area Commander for insubordination.
