What we did on our holiday is a hilarious journey through an unforgettable family holiday as a couple attempt to keep their impending divorce secret from their extended family.doug and abi and their three children travel to the scottish highlands for doug's father gordie's birthday party, where it's soon clear that when it comes to keeping their secret under wraps, their children are their biggest liability.from 9 year old lottie's notebook to keep track of the lies so she remembers which ones to tell, to 4 year old jess's perverse attachment to a brick named norman signalling her maladjustment a mile off, the parents are kept on tenterhooks and a week has never seemed such a long time.but it's middle child mickey and his granddad's shared passion for vikings which gives rise to the most far reaching and unexpected consequences, when a day at the beach turns to tragedy and the children take matters into their own hands.
