"Targamadze, Razvozzhayev, Udaltsov and Lebedev - together with unidentified individuals - organized mass riots on Bolotnaya Square on May 6," he said.

An authorized rally on Yakimanka Street and Bolotnaya Square ended in clashes between the police and protesters. Dozens of indivdiuals were injured and over 400 protesters were detained. The Investigative Committee launched a case over the mass riots.

The film claimed that the opposition was organizing a coup using funds from abroad and showed Left Front movement coordinator Udaltsov and his companions allegedly talking with Targamadze, who at the time headed Georgia's Parliamentary Defense and Security Committee, and is said to have been involved in planning the "color" revolutions in Georgia and Ukraine, as well as the mass riots in Belarus.
