For the happy couple this is the biggest night of their lives. But it’s just another of many for Max, from the catering company, Guy the photographer, James the singer, and everyone else working at the event. Pierre and Hélène have decided to celebrate their marriage in a beautiful 18th century castle on the outskirts of Paris. We follow the occasion from its preparation until the sun comes up, almost in real time, but only seen through the eyes of those working at the marriage. This will be a night full of surprises.
