The SBD is under the Cottage Hospital, and Austin wants his cut of the action. Bradley refuses the offer, and Austin knocks Bradley out and has him taken to the Cottage Hospital to recover. Bradley wakes up just in time to panic.

Jack is discharged from the hospital a changed man, and now he is in love with Charlotte. Isobel does not take the news well, and neither does Jack's mother.

Doctor McDuff thinks he has cured Lady Patience now that she can walk. The King is on His way to lay a foundation stone at the Hardacre Memorial Privy, and Charlotte gets the idea to protest the new rent hikes, by riding through town naked on Brass Beauty. Isobel is determined to join the protest, but Big Tom, the huge chimney, is starting to wobble with Matthew and Jack sitting on top.

As the Prince lays the new stone at the Cottage Hospital, McDuff drops his trousers and Isobel and Charlotte arrive naked on Brass Beauty protesting about the rent increases, then the mortar on the trowel explodes due to SBD.

Austin tells the family he thinks Bradley is insane. An epidemic is raging and McDuff says the cause is the convenience at the back of the munitions factory. Bradley gives Prudence SBD and then takes advantage of its effects. She wears him out. Bradley tells George to keep using the convenience and McDuff and Agnes wire it up to explode.

Bradley gets out of being certified and turns the tables on Austin. George, blackened but alive, is returned home. Bradley decides to sort out Simon Pugh and help Austin win the election with the help of Mrs Marchington, his father's chiropodist and SBD.

Austin hears Lord Sodbury has died at the chiropodist's which means Seymour Pugh will go to the House of Lords and it will be a walkover for him at the by-election. Jack fails to dissuade Isobel from marrying Mountfast, but she guesses he's done a deal with her mother and tells him her reason is money and she'll look after him.
