When Gemma shirks responsibility once too many and announces she’s off to the Caribbean (again!); Juliet finally snaps. Gemma offers her sister the perfect solution - to swap Christmases: she’ll stay home and cook the turkey (how hard can it be?) and Juliet can fly off into the sun and have a restorative break.In the midst of all the chaos, there’s Will, Juliet’s dishy neighbour who’s far too nice to float Gemma’s boat and may secretly harbour feelings for her sister; and Marco, the suave Italian in the villa next door, who has his own ideas about the best way to help Juliet unwind. Will the sisters abandon caution and make this a Christmasswap to remember?
