On the enchanting Isle of Arran, three sisters find themselves at Meadowbank Cottage, their childhood home. But it's the first time they've been together since their mum died. And now they're back in Arran for the wedding of middle sister Emma. Eldest Kirsty is juggling the responsibility for Meadowbank Cottage with an earth-shattering secret she discovers in the attic. Bride-to-be Emma is an ambitious lawyer living and working in Edinburgh. Far from turning into Bridezilla, she's looking forward to a simple ceremony. Meanwhile baby sister Amy lives in Vancouver, but she wonders if she should extend her trip to Arran, maybe even for good…One thing is for sure: there's going to be lots of laughter and buckets of tears along the way. But how will the sisters come together when Emma receives some unexpected news?
