Vincent was born near Paris, but has cut off every link with his roots. Maria, fifteen years younger, grew up in Ostia, but no longer sees her family. Together they form a couple that does not seem to need anyone. They lead a secluded life in contemporary Rome, indolent and distracted. Furthermore, Vincent and Maria are good at blending in with their environment. When they return home, they make love with the passion of young lovers in a suburban apartment that she has carefully furnished. Yet, on closer inspection, their everyday life betrays what lies behind their seemingly normal appearance: a project carried out by him with a clear determination and accepted by her only by virtue of unconditional love. A plan to help couples who cannot have children. Maria decides that it is time to create a real family. This choice has an inevitable consequence: the rebellion against Vincent, the man of her life.

Vincent est né à Paris il y a 50 ans, mais a coupé les ponts avec les siens. Maria, 35 ans a grandi à Ostie en Italie mais ne voit plus sa famille. Ils vivent ensemble à Rome, s'enlaçent dans le métro, se dévorent des yeux au restaurant, font l'amour comme au premier jour... Un quotidien parfait. Sauf qu'ils n'ont pas d'enfant et que Maria est prête à tout pour en avoir un.

Roma, oggi. A un primo sguardo Vincent, cinquantenne francese che delle sue origini ha mantenuto soltanto l’accento, e Maria, di una quindicina di anni più giovane, sembrano una coppia simile a tante altre. Quando prendono il metrò, si siedono vicini, abbracciati. Quando tornano a casa, fanno l’amore con passione, legati a doppio filo da un’attrazione reciproca che di solito caratterizza gli esordi di una storia d’amore, e non i rapporti consolidati come il loro. In una quotidianità vissuta prevalentemente al riparo delle mura di casa, anche la presenza di persone esterne sembra non soltanto superflua, ma persino evitata, come se entrambi bastassero all’altro e il resto del mondo non avesse importanza o, addirittura, non esistesse.
