It's April in 1940. The Nazis are occupying Copenhagen. As they march through the streets, a stark realisation hits the physicist Niels Bohr. He has hours - maybe less - to make two Nobel Prize medals disappear completely. What might a substance named Aqua Regia and a humble beaker do conceal two huge lumps of gold? And bring it back again...a decade later.
