An ex-friend's request for friendship on facebook is never fun... especially when she died 15 years ago.

Clara, a young Parisian journalist, has recently made perfect love with Gabriel, her neighbor. One evening the latter receives a strange invitation on Facebook: that of Aurelie Massoni, his girlfriend when he was a teenager and lived in Marseille. The problem: Aurélie died mysteriously more than 15 years ago! A few days later, Gabriel disappears after sending an email enigma tick to Clara. Convinced of the link between this intriguing request for a friend and the sudden disappearance of her lover, Clara decides to go to the Phocaean city to find him. The young journalist begins an infernal dive in Gabriel's past. Why are locals so reluctant to talk about the news that marked their summer of 1995? What happened on the night of Aurélie's death in this sordid bar where all night owls from Marseille gather to consume drugs and alcohol excessively? Between neighborhood dramas, family secrets, betrayals and mafia corruptions, Clara will quickly understand that all the old friends of Gabriel do not want him that good.
