Each of her children expresses dissatisfaction with their lives and reveals information Elizabeth did not know. Argentina invades the Falkland Islands, and Thatcher demands action to recover them. Mark Thatcher is found in Algeria. Diana is pregnant, and her relationship with Charles has deteriorated. He tells Elizabeth that he is still in regular contact with Camilla.
