Christmas-phobic, commitment-phobic Holly has left her fiance at the altar in London. Desperate to escape the repercussions of her decision, she flees home to Ireland to work as personal assistant to the incorrigible Serena Harper - the ageing, still glamorous proprietor of Knockboden, a beautiful but crumbling country house in the foothills of the Dublin mountains.

What Holly doesn’t expect is that Knockboden is to be the location for a Reality TV Christmas Special, in which high profile social media couple Jake Lyford and Olivia Stack plan to live stream their wedding on Christmas Eve. Holly has six weeks is to get the house ‘Insta-ready.’

Serena’s handsome, tetchy and recently divorced son Tyrone strongly disapproves of the house being farmed out for showbiz. While Holly wrestles with the irony of working on a Christmas wedding show, she realises that, even with the TV cameras rolling, her new boss Serena can no longer afford the upkeep of her beloved home.

As the Wedding Day approaches, and plans for the wrap party crescendo, both Holly and Serena are about to discover that Jake and Olivia might not be the only ones about to get their happy ever after.
