The Nagazi cartel, operated by brothers Zurab (Tornike Gogrichian) and Davit Radiani (Tornike Bziava), reigns supreme in Georgia, having risen to power through their drug and weapons business to the extent of commanding a literal army of extremely loyal soldiers, not to mention having most, if not all, of the government officials and politicians of Georgia in their pockets. Note the similarities to Amir Asif in the first film, who also had most of the Bangladeshi government on his side However, U.S. intervention into the Nagazi cartel's dealings complicated matters, resulting in Davit killing a DEA agent.
This incident caused American authorities to increase their pressure on the corrupt Georgian officials owned by the brothers, including the Governor, who contested Davit's extradition to the U.S. and allowed him to stay in Tkachiri Prison in Georgia with his wife and children. Davit's protective elder brother had no choice but to wait for Davit to finish his sentence, but later found that the Governor signed off on extending Davit's sentence by 10 years. Despite the Governor's pleading that the Americans gave him no choice, an angered Zurab murdered the Governor in cold blood.
Rake had long known the brothers through his then-wife Mia, whose sister, Ketevan (Tinatin Dalakishvili), is married to Davit. However, when Rake last saw the brothers eight years prior to the events of "Extraction 2," they had been operating petty crimes on the street level and weren't as formidable of a threat as they proved to be in the film.
