Nick returns to Blackwall. Pearce tells him about Pitbull's racist abuse, about Carole's bungled shout and his wish to be Sub Officer. He also welcomes Skip, then reprimands Carole about the shout. The watch has a good laugh, when a biker turns up at the station, his hands and butt glued to the handlebars and saddle of his bike. Beattie and Kelly go to visit the new health club, while Billy visits Skip . During the next shift, Carole admits to the watch that her husband injured himself off-duty and not heroically on-duty as he always says. Blue Watch is called to assist the police, who are trying to save a young woman who intends to jump off a high building. Skip gets his chance to prove himself and scares everyone with his rather unorthodox but successful method. "Macbeth" is being staged in prison and Sicknote's brother escapes in the van with the costumes and props. Sicknote wants to take him back, but he runs off. Jean urges him to tell the police, when the cops ring at their door, arresting them for assistance! During night shift, Jack tells Carole the whole story of how his friend died because a Sub Officer gave wrong orders and his BA ran out of oxygen.
