It actually centres around Yeltsin not Gorby.

Off wikipedia:

He vowed to transform Russia's socialist command economy into a free market economy and implemented economic shock therapy, price liberalization and privatization programs. Due to the method of privatization, a good deal of the national wealth fell into the hands of a small group of oligarchs.[2] Much of the Yeltsin era was marked by widespread corruption, inflation, economic collapse and enormous political and social problems that affected Russia and the other former states of the USSR. Within the first few years of his presidency, many of Yeltsin's political supporters turned against him and Vice President Alexander Rutskoy denounced the reforms as "economic genocide".[3]

Ongoing confrontations with the Supreme Soviet climaxed in the October 1993 Russian constitutional crisis in which Yeltsin illegally ordered the dissolution of the parliament, which then attempted to remove Yeltsin from office. The military eventually sided with Yeltsin and besieged and shelled the Russian White House, resulting in the deaths of 187 people. Yeltsin then scrapped the existing constitution, temporarily banned political opposition and deepened his economic experimentation.
