The winds of war blow across Walton's Mountain-- 'Yesterday, December 7th, 1941 - a date which will live in infamy...' An unflinching President Franklin Roosevelt responds to the Japanese attack on Pearl Harbor as the nation - and the Waltons - plunge into the chaos and heroism of World War II. John-Boy reports from London for Stars and Stripes. Mary Ellen nurses the war wounded. Jason, Ben and even Jim-Bob debate joining up. John and Olivia expand their lumber business to aid in the war effort. But the personal events are almost as dramatic: Still reeling from Grandpa's death, the family experiences the sorrow of losing another family member... and the surprise of gaining a new Walton.
