After Ksenia Sobchak, a public person and a journalist, had been nominated to run for Russian presidency, her offices and volunteer groups launched activities in the regions. In Rostov-on-Don, Mineralnye Vody, Sochi, and Volgograd, the "Caucasian Knot" interviewed supporters and volunteers of Ksenia Sobchak to find out what to expect from the "candidate against all" and why she is more preferable than Putin and Navalny. Rivals and opponents of Ksenia Sobchak also had something to tell about her.

For more than 10 years, in an outskirt of Grozny, a secret oil refinery has been operating. It is situated at the exit from the Zavodskoy District of the city in the direction of the dwelling settlement of Andreevskaya Dolina. This was reported in a letter sent to the "Caucasian Knot" by one of Grozny townspeople. Residents of other places of Russian South – of the city of Tuapse and Dagestani countryside – told about their personal experience and consequences of living close to oil refineries.

The "Caucasian Knot" tells why it is not easy to return militants' children to Russia, who is engaged in the process, and how many children they have already managed to return.
