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 C.I.A. 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 K.G.B., 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.
