Her friend, doctor Peter Husak, introduces the American Jack Carver to his friend nurse Kate - and it's love on first sight. But when she learns in a dramatic incident that Jack's a CIA agent, she leaves him and marries Husak instead. Together they go into a war area in Nagorny Karabach for a relief organization. When Kate finds out that Husak is willingly cooperating with the KGB, she leaves him and asks Carver, who's about to bring a businessman out of the country, to take her and her baby with him on a dangerous flight.
