Adrien Mullet de Lespinasse comes from an illustrious lineage of aristocrats and seems to hold all the cards to be a happy man. But despite his dashing looks, wealth and success, he has always felt at odds with himself in this close upper class 'club' which he was born into and where outsiders are seldom welcome, regardless of the friendly and eccentric image its members give to the outside world. The Covid crisis brings this same world into lockdown and gives Adrien the opportunity to reflect. The discovery of the private journals of his direct ancestor, an adventurous Viscount who left France on the verge of collapse in 1789 to sail the oceans before settling down in a faraway Indian Ocean colony now called Mauritius will make him travel through time and completely change his outlook on life.
