The life of Juulia, a Finnish parliamentarian, is suddenly turned upside down by the discovery of the betrayal by her husband Matias, a Protestant pastor, with the young Enni. After an initial moment of anger and desperation, Juulia realizes that she cannot leave him and she understands that sometimes it is possible to sacrifice a part of one's individual happiness for the good of the people you love. For this reason she suggests to Matias that they open their relationship, a choice that will lead her to meet Miska, a young non-binary, who is also her girlfriend, and to experiment with polyamory naturally and spontaneously, with all the consequences of the case, positive and negative.
