The Lost Leonardo tells the inside story behind the Salvator Mundi, the most expensive painting ever sold. Auctioned at a record-breaking $450 million, the piece is believed to be a long-lost masterpiece by Leonardo da Vinci. From the moment it is purchased from a shady New Orleans auction house, the fate of the Salvator Mundi is driven by an insatiable quest for fame, money and power. But as its price soars, so do questions about its authenticity. Is this multi-million dollar painting actually by Leonardo – or do certain power players simply want it to be?

A discussion follows the film.
