Romance and dystopia often go hand in hand. Léa Seydoux is Gabrielle, a woman who lives in a futuristic society that abhors emotions that exalt human beings. To this end, a DNA purification process is carried out that leads the individual to travel through all their previous lives, separating themselves from all the things that have affected them. On these journeys, Louis (George MacKay) appears, in an encounter that jeopardizes the whole process.
