London, 1993: English teacher Crystal hears of the terrifying kidnap and torture of a student from war-torn Georgia, then sees a Colombian student receiving a huge sum of cash. She stumbles into a deadly conflict between a Colombian drug cartel and the Soviet Mafia: if either of them realise how much she knows, they will not let her live. Meanwhile junior New York stockbroker Mistry suspects a client is using her to launder money, then finds a Trojan virus is stealing the bank's data. When someone tries to kill her, Mistry must use every resource her bank can offer to find out the truth... and who she can trust. As the net tightens around Crystal, and Mistry's assassin tries to kill her again, the women realise their only hope is to unite forces. But are they in time to save each other's lives?
