It's Christmas, and a time for the family to be together. But Craig is sick of being constantly criticised and decides to move back to his mum's for a while.

Lauren and Craig return home to celebrate Mum and Mike’s first wedding anniversary, but when Declan drops a romantic bombshell on Lauren and Dad drops an explosive one on Millie, everyone’s future is turned upside-down. Will Lauren say yes to Declan? Will Millie accept dad's proposal? Can Fran and Jake’s hair swear avoid them being caught in the middle in a tug of war between Scotland and Spain?

Millie sneaks off to Spain to convince Dad he should come home, and Craig insists on going with her as a wingman. Amber comes back to get Fran and Jake, but they really don’t want to leave. Mike learns that Craig has left music college to pursue his dream of being a DJ. Can Fran and Jake continue to hold out against Amber’s Spanish temptations? Will Craig find a club that wants him? What does Millie do to get Dad back to Scotland?

Craig shows Millie his new beach club and tries to convince her that Spain really suits her dad. But Millie has dug herself a pretty deep hole and they have to race against time to save her dad’s job. Can Craig actually be of use and help Millie put everything right before it's too late? Meanwhile, Amber has convinced Jake that Spain will be good for them all. Jake asks a really big favour of Mike and Sharon to help Fran, and the families might end up more mixed up than ever!
