A detective trainee named Jean Eyben is commissioned by the Hutte agency, where he works, to follow the trail of a woman. The woman is named Noelle Lefebvre, and the young investigator pursues her unsuccessfully. Thirty years later, he takes up that case on his behalf and continues the investigation. In those two time periods, Eyben goes in search of a ghost. He walks the streets where she walked, tries to find a letter, locates an address book, talks to people who knew her, and sniffs around her perhaps hectic sentimental life. What emerges are vague clues, echoes of the past: a Chrysler convertible, a certain Sancho, a summer, a lake, an aspiring actor... Shadows, snippets of memory, memories that time distorts or erases. Who is Noëlle Lefrebvre, the woman on the run, the vanished woman? And who is Jean Eyben, the man who follows in her footsteps, the man who lives haunted by her absence?
