Hallam is sent to train on the fire brigade river boat on the Thames and Pearce takes over as Sub. Jaffa attacks Sicknote about fleas in the station and Nick has a go at him about the dog. The whole watch has to clean the station from attic to cellar as Nick fears another surprise visit from Scase. Down in the cellar, Billy finds some old uniforms. Blue Watch is called to a block of flats, where a young woman has cracked up and locked her husband and child on the balcony. She attacks Recall and Sally with a knife when they enter the flat, but they can overpower her. Bayleaf signs the contract to buy the restaurant and George starts another job as watchman in a theatre. Sandra, sick of Hallam's attitude, has a job interview herself. Billy is preparing another prank on Pearce and pours foam pulver into the toilet, but it almost turns into disas ter when Scase appears at the station and intends to use the toilet, which is blocked. When he leaves, Billy sends Pearce to check on the blocked toilet and he unblocks it - getting covered in masses of foam, much to the watch's amusement. A blaze on the Woolwich Ferry brings Blue Watch together with Hallam and the river boat crew. Uncle Yanni tells Nick to leave Ariadne alone now that she's a married woman. Sally's boyfriend turns up at her flat and they have an argument just as Kevin appears. Kevin punches him, thinking that he's doing Sally a favour, but she yells at him. (thetvdb.com)
