Sean Connery and Michelle Pfeiffer both deliver exceptional performances as two people - he from England, she from Russia - caught up in a world of spies and politics, whose love could prove fatal to them both. When Katya, a beautiful Russian book editor attempts to send British publisher Barley Blair a manuscript written by "DANTE", a noted Soviet scientist, she unwittingly involves him in a world of international espionage. Having met Blair at a dinner party, Dante trusts him to publish the manuscript, which contains information that could alter the balance of world power. But before the manuscript reaches Blair it is intercepted by the West's spy-masters, who then send Blair to Russia to gain more information on the mysterious manuscript. But when Blair falls in love with Katya, he must decide whose side he is really on.
