Boston, Massachusetts, 1985. Boonie's 18-year-old adopted daughter, Karen, meets with Dr. Richard, working in a birth clinic for pregnant women, to question him for facts about her real mother K.C. A flashback to 1966 shows a pregnant K.C. questioning her romantic involvement with Lt. Col. "Mac" Miller, which ends when he's wounded in action and sent home, and Lila arrives to replace him as commander of China Beach.
