The Conquest is a 2011 biographical film written and directed by Xavier Durringer.
"May 6, 2007. France’s run-up to the presidential elections.
As the French people are getting ready to go to the polls to elect their new president, Nicolas Sarkozy has shut himself away in his home. Even though he knows he has won the battle, he is gloomy and looks despondent in his dressing gown. All day long, he has been trying to get in touch with Cécilia - to no avail.
The last five years unfurl before our eyes, recounting Sarkozy’s unstoppable ascent, riddled with backstage underhand trickery, fits of anger and confrontations.
THE CONQUEST is the story of a man gaining power and losing his wife. "
