It is Millie and Lauren's first Christmas since the separation, and for Millie it is the chance for a fresh start - for once, a Christmas without family arguments.

She persuades everyone to leave their Christmases past behind, and invent new traditions for the new family. Some people struggle with it - especially Lauren, who wants everything to be like her rose-tinted memories - and Millie realises her grand plan is creating as much conflict as it resolves. But eventually, they all start to realise what it is they really value - and that Christmas traditions needn't all be bad ones.
