A mysterious seller appears with a seemingly endless supply of ancient, precious gems at bargain prices. Collector and dealer Ittai Gradel snaps them up. But then a strange series of events starts to unfold.

From his home in rural Denmark, Ittai becomes suspicious about what is happening hundreds of miles away at the heart of the British Museum.
