Once Upon a Time in the East (2011)

Bulgaria being part of the Eastern bloc joined the race for freedom and democracy during the 1990s. Thousands flooded the streets speaking their minds with blistering hopes of developing new democratic forms of society. Within a few years the new systems of government transformed released criminals, prisoners and other sportsmen, mainly wrestlers into groups of street gangs, racketeers and security companies. With these gangs of thugs the newly appointed democrats privatized the country... 20 years later one man stood out to tell his and their story...

A former wrestler himself – Georgi Stoev.
