Bernard chokes to death on a boiled egg while his wife looks on. Juliette watches him suffocate without intervening and, as though waking from a long sleep, she abruptly leaves their house, marching straight ahead. Arriving in Havre by chance, she tries to board a freighter, but must wait 48 hours. In the port, she encounters Santiago, a young man who sells chips from his father's mobile stall. Juliette and Santiago immediately fall for one another and promise to leave together for Argentina to live in the pampas.
Santiago is torn between his dream and the ties that bind him to his father. The latter wants to open a snack bar for his son and to go into business with him. Juliette waits. In spite of everything, she wants to be able to trust.
Bernard isn't dead. He decides to set out to find Juliette, only to find that she has vanished again.
But what people who have crossed paths with her tell him seems unreal. When the question "where is Juliette?" is asked, another takes its place: "Who is Juliette?"
