When Doug (David Tennant) and his family travel to the Scottish Highlands for his father's (Billy Connolly) birthday party, hilarity ensues as they embark on what will no doubt be a holiday to remember. Along the way there will be plenty of time spent allowing the children to drive and verbally battle with their grandfather. That, and debate with their Uncle Gavin (Ben Miller) whether he is rich or not and how he is able to live in such a big house.
Doug and his wife Abi (Rosamund Pike), soon learn that trying to keep secrets from the rest of the family can be difficult when their children are most likely to spill the beans out of any of them. What follows is a heart-warming family comedy from the creators of the hit BBC television series Outnumbered. What We Did On Our Holiday is a truly British comedy with plenty of heart, as Doug and Abi soon realise that whatever problems there are in their relationship, they can be put aside for this time spent with their family. As Billy Connolly says, "none of it matters. None of this stuff."
