1940. As Soviet forces storm Lithuania, Zofia and her brother Jacek must flee to survive.

A lifeline appears when Japanese consul Sugihara offers them visas on one condition: they must deliver a parcel to Tokyo. Inside lies intelligence on Nazi atrocities, evidence so explosive that Nazi and Soviet agents will stop at nothing to possess it.

Pursued across Siberia on the Trans-Siberian Express, Zofia faces danger at every turn, racing to expose the truth as Japan edges closer to allying with the Nazis. With the fate of countless lives hanging in the balance, can she complete her mission before time runs out?
