Didier Travolta (Franck Dubosc) is a 40-year-old disco music fan who has no job, lives with his mother, and has a son he hasn't seen for a while. The mother of his son refuses to send him their son for the holidays unless he can offer him a real vacation, not just going to bars of the French port city of Le Havre. As the jobless Didier has no money, the only way he can see his son is by winning a dance contest organized by his friend Jackson (Gérard Depardieu), with the prize a vacation to Australia for two.
