Antoine loves the nightlife and will try any trick to get himself in the most exclusive nightclubs in
Paris. One evening, when he is refused entry to a fashionable club, he claims to be a buddy of the mysterious Jordan, a famous party animal. The trick works, but Antoine is then approached by Von Bulow, the owner of the place, who wants to get in touch with the aforesaid Jordan. Antoine is recruited to find the elusive character, who never goes anywhere without his sister, Violaine, a dangerous vamp. With his buddy Étienne by his side, the young man hunts through the night for the couple, and ends up confronting many dangers.
