This footage was captured by a secret KGB agent that was asked to film an investigation.
The agent arrived at a secret under ground base. Once inside the base he noticed a lot of locked doors.
He told UFO today that he heard sounds of creatures that were not of this world.
Than he was led into the chamber where the alien was kept.
The other people that joined him put on protective suits but the assured him that he was not in any danger.
Once he entered the room in which the alien was kept, he heard the alien talking in his head. The alien kept asking him to contact his superiors in order to get out of the prison.
