New York, September 1997. The young Cécile is a student at NYU (New York University). One of her professors is a famous writer: Serge Doubrovsky, pope of autofiction. A very strong filial relationship quickly develops between the young girl and the professor and very soon, she moves in his flat. Indeed, he moves to Paris and sublets her his New York apartment. Over the years, the young woman and the aging writer see each other regularly, here and there, in Paris or New York, they dine together, get to know each other more and more intimately by exchanging on literature and life. They have no secrets from each other, there is absolute trust between them. Pygmalion or surrogate father, Doubrovsky alias Doudou is neither for Cécile. At least she likes to believe it and to make him believe it. But perhaps she is deluding herself... When Serge suddenly offers to Cécile to marry him and give him "the prestige of his name", their beautiful story changes and their paths diverge...
