For both selfless and selfish reasons, the United States institutes the Marshall Plan, giving massive amounts of aid to the war-ravaged countries of Europe. Suspicious of American intentions, Stalin prevents countries in the Soviet sphere from taking part in the plan. As a counter to the U.S. plan, Stalin established the Council for Mutual Economic Assistance.
In Czechoslovakia, communists seize power in a 1948 coup.

The Marshall Plan successfully modernizes Western Europe and strengthens its ties to the United States. Interviewees from episode 3 include Vladimir Yerofeyev, Gianni Agnelli and Giulio Andreotti.
