From The Desert of Forbidden Art movie site:
How does art survive in a time of oppression? During the Soviet rule artists who stay true to their vision are executed, sent to mental hospitals or Gulags.
Their plight inspires young Igor Savitsky. He pretends to buy state-approved art but instead daringly rescues 40,000 forbidden fellow artist's works and creates a museum in the desert of Uzbekistan, far from the watchful eyes of the KGB. Though a penniless artist himself, he cajoles the cash to pay for the art from the same authorities who are banning it.
The Karakalpakstan State Museum of Art, also known as the Nukus Museum.
