A former police major, Korenev, nicknamed The Fox, after participating in the liquidation of a band of terrorist bandits, continues to fight against evil in all its forms.
This time fate has led him to a clinic, where he is resting. But when a series of acts of banditry against people he knows take place in the city, he cannot stay away. The banker Khondatchev and his collaborator Katia get Korenev out of the clinic and ask him to help them. The investigation leads Korenev to reconnect with his old environment in spite of himself, turns his life upside down, and makes him find true love.
