Based on the 2016 Danish series created by Mette Heeno, Splitting Up Together is the story of a couple whose marriage is reignited by their divorce.
After breaking the news to their friends and family about their divorce, Lena has to deal with her son Mason's growing pains. Meanwhile, Martin, still feeling guilty about refusing to dance with Lena at their wedding, secretly tries to atone for his oversight and surprise his ex-wife with new moves.
With this being Martin's week in the house to take care of the kids, he discovers that daughter Mae finds his parenting skills to be lacking and a bit sexist. Meanwhile, Lena's time in the garage gives her time to contemplate going out with a handsome doctor and perhaps taking the relationship to the next level.
