Martin prepares to face his hearing, but despite having closed the practice, he finds all his patients are trying to make appointments. An American tourist who visited Portwenn previously returns to the town, hoping to research her family tree.

Louisa has problems at school with Toby, Angela Sim’s Nephew. Meanwhile, Al has a ‘Large Whiskey’ order and has to ask Bert for some help, and Mrs Tishell seems to be having a delayed onset of mourning. Elsewhere, Martin and Louisa decide to try Mel’s suggestions of using amber beads to help James while he is teething.

Penhale decides to have a Police Open day to raise community awareness, but the only genuine visitor is an angry farmer who has had three of her sheep stolen. Meanwhile, Morwenna decides to take Al away for the weekend to try out Hannah’s new glamping site, but the trip does not go well as Al accidently burns down the yurt. Elsewhere, James has started biting not only Louisa but other children at the nursery. Louisa speaks to Tina about it, but is surprised to find out Tina has spoken to their lecturer about it too.

Martin wakes up to an empty bed. When he goes looking for Louisa he discovers she is trying to write her resignation letter.

However, the reunion is tinged with sadness when it turns out that Morwenna’s mother has liver cancer, and has decided against treatment because of her faith. Louisa’s first online call for her new course does not go as planned – especially when Martin tells the lecturer exactly what he thinks – and Joe investigates a break-in at the school where nothing has been stolen.

Martin and Louisa search for a nursery now that Janice has left, and Mrs Tishell is shocked to find out that Al has very high blood pressure.
