Paris and its mysteries... For centuries, the most wonderful intrigues have been woven in the Louvre, a haven of culture and history. An intrepid young woman enters this universal temple and unwinds the skein of time. After an encounter with the Mona Lisa and the Italian masters, armed with a key, she releases the secrets -- also desired by a man hot on her heels -- enclosed for more than 150 years in a legendary trunk created by Louis Vuitton. Like a thread stretching across time and space, a hot-air balloon rises above the Cour Carrée. The beautiful unknown woman leaves the Louvre for a far-off destination in pursuit of her destiny.
