32-year-old Lili David is the single mother of a teenager. Her own mother is an energetic biker nicknamed Ma Dalton. But everything is wrong in Lili’s life: no job, no money. Sophie, her son’s stepmother, offers Lili a job in a luxury 24/7 "life services" company. It's a magical job that consists of fulfilling people's every need and desire: finding a private jet for immediate use, organising a middle-aged wedding, locating Michael Jackson to celebrate a birthday party, helping a financial tycoon gather his long-lost family around him a few days before his trial… The list of demands is infinite, a symptom of the ever-increasing whirlwind of our consumer society. Like a modern-day fairy granting wishes, Lili David gives it her best shot, and seems to have everything well in hand... everything, that is, apart from Marc, a bashful ex-lover having undergone a makeover as a playboy, who shows up in her life after a 5-year absence... as her colleague!
