December 1991 saw the end of 70 years of communist rule and the collapse of the Soviet Union. We hear from two of the key signatories of the dissolution treaty, a witness to the ensuing crisis in one of the newly independent states, and from an American nuclear expert who helped clean-up the former USSR. Also, the performance artist protesting about the growing divide between rich and poor, and the first editor of Vogue magazine in Russia.
