July 2017: it’s been one year since the "Brexit means Brexit"! movement began. The moonstruck Marguerite Fiorel, 17 years old, a young French soprano, has come to London to sing in The Marriage of Figaro. At her side is her beloved professor, Pierre Kamenev. The duo will meet a flamboyant English Lord, Cosmo Carraway, and the electric Justine Dodgson, creator of a secret start-up, Brexit Romance. Its goal is to organize sham weddings between French and English young people... to get the latter European passports.
But these alliances will mean a lot of headaches… and heartaches !
