Former criminal investigator, Major Korenev, nicknamed Fox is released from prison. He has been detained there as a result of planted incriminating evidence of unlawful investigation techniques. Setting accounts with Shaman - a big criminal boss, who ordered the evidence planted and also with his former colleagues was not a part of Korenev's agenda. As he returns to Moscow he finds a new world ruled by underworld bosses, criminal clans fighting each other and utter chaos on the desperately keeping appearances streets of Russian capital. Facing death of his friends, Major Korenev decides to re-install law and order using some unorthodox methods that are only relevant in 21st century Russia.
