Olivia and Anthony are planning A Very Extravagant Wedding at the newest hotel on the tiny Scottish island of Mure. They're flying in chefs, musicians and something called a living flower wall... and no one is even allowed to think the word bridezilla.

Flora is trying - and failing - not to let Olivia and Anthony's wedding distract her from planning her own big day with Joel. But the couple have wildly different ideas about how to celebrate and somehow, just when their relationship should be plain sailing, everything is suddenly very hard indeed.

And then there's Lorna and Saif. The local headmistress and the GP desperately keeping their relationship a secret to protect his sons. But while they're looking out for the boys, who's looking out for them?
