在这部卢浮宫谜案悬疑/犯罪片中,Mercure是巴黎上流社会钦佩或敬畏的着名强盗，实际上是个女人，当晚在卢浮宫博物馆展出的那一晚，他们偷走了属于尤金妮皇后的珠宝，就算是精打细算。
Mercure, a famous robber admired or feared by Parisian high society, is in fact - a woman. Constance de Coulanges - her real name - is about to pull off a masterstroke by stealing a set of jewels that belonged to Empress Eugénie on the night it is displayed at the Louvre Museum. To do so she hires Frédéric a handsome tightrope artist. Their endeavour becomes even more dangerous when Chief Inspector Thénard puts a price on Mercure's head and places the Louvre under tight security.
