The Larkins dash to the railway station and manage to stall Mariette's departure to France. They convince her to stay for a donkey derby/gymkhana and cocktail party in a few days.
Pop is in denial, and Ma issues him some tough love while playing Cupid between Primrose and Rev Candy. Pop's old friend Fruity Pears arrives to the village with his fairground in tow, but it's not all candyfloss and laughs.
It's BBQ weather, and no-one throws a party like the Larkins - everyone is welcome, including the dubious Jerebohms. Truths and tension are served alongside the sausages and burgers, and a trap is set to bring Pop down.
Ma and the children try to convince Pop to take the court case seriously, but he has more fun things on his mind. He is conducting his own defence in court. Meanwhile, Mariette and Charley make a welcome return home.
The Larkins do all they can to get Pop out of prison. To keep Pop's spirits up, Mariette tells him he is going to be grandfather, but swears him to secrecy. Ma is surprised by an about-turn from a conflicted Norma Norman.
News reaches Pop that the train station is to close. With the help of reluctant Miss Chand and villagers, Pop seizes the opportunity to save the railway - and make money along the way. Mariette fights with Pauline, and Charley makes a big decision.
Ma is worried that Pop is working too hard and books a weekend in Margate, leaving Charley and Mariette to mind the kids. Margate, however threatens to be a let-down.
With their wit, charm and a little bit of cunning, the Larkins woo Charley the Tax man. Mariette agrees to put her plans on hold and stay free for the summer.
