Overview: It's the day of Billy's Nan's funeral and Billy is off on compassionate leave and Clingfilm is covering for him. Due to Nick being in Holland, Carol is in charge and Pearce is promoted to Sub Officer and it is obvious he does not like a woman being in charge. Meanwhile Nick arrives in Holland and is met by Marianne, who we first saw in series 9, then as the two share a quiet moment together her pager goes and her and Nick attend a shout. It's a woman drowning and as Nick and Marianne are first on scene Nick heroically jumps into the water to save the distressed woman. However Marianne is not impressed. Meanwhile back at Blackwall Sicknote makes friends with Acer a dowser who is looking for an ancient underground river. While off duty Pearce visits Sandra Hallam and Gregg visits Tiggy at college, although due to confusion he ends up standing in as the live model for art class. On the next duty the lads play a joke on Sicknote making out there is a Blackwall ghost and the Watch attend a shout at a neighbouring Fire Station where Clingfilm's camper van is alight. On Clingfilm's return to the station Pearce tells him of the news and Recall reluctantly agrees to have a new lodger - Clingfilm. The Police say its arson, could it be his estranged wife Noreen?
