Alain Juppé is known to be a plain, hardworking, cold and brilliant man. In the 90's, all French political men, from François Mitterrand to Jacques Chirac, saw a great futur for him.

In this frame, Franz-Olivier Giesbert followed him during several months, trying to understand the personnality of this reborn political leader.
