L\'Emploi du Temps aka Time Out (Laurent Cantet, 2001)

Vincent, a corporate consultant, has been fired but doesn't tell his wife and three children. Instead he goes out on long, hypnotic drives to Switzerland where he sleeps in his car, wanders hotels and corporate headquarters, and eventually pretends to be working at an important new job for the UN. This life seems to suit him more than his real job ever did. Later to make up for his lack of income he develops a scam whereby he gets friends and former coworkers to donate money expecting a quick return on investments in the Third World. A shipper of illegal imports and knockoffs spots Vincent and recruits him to help with his business. Family and friends eventually realize they're being duped and Vincent is in all kinds of deep trouble, but the ending is not what one would expect.
