Yevgeny Kopylov, the executive director of a large firm, is being blackmailed into paying back a large debt. Soon Kopylov disappears, and his wife finds a bill of exchange for 10 million dollars at home and begins to search for her husband in the morgues.

The robber attacked the exchange office, but was so nervous that he took quite a bit from the safe. Nevertheless, the cashier claims that the thief stole everything from the exchanger that was there. Mukhtar helps to convict the cashier of theft.
