The project tells about the closed world of the Russian prison through its specific language. However, the concepts and slang words that prisoners use in their speech perfectly illustrate what is happening not only in the zone. The heroes of the project are people convicted under various articles, both political and criminal. Businessmen and entrepreneurs, artists and activists, policemen and workers, DJs and officials, writers and professional thieves, men and women - they all become guides to the world of prison.
