'O.R.U.J.I.E' is an abbreviation of the names of friends: O - Oleg, military pensioner; R – Roman, scientist, employee of the Research Institute; U – Ulyana, television correspondent; Zh – Zhenya, physicist, Doctor of Science; I – Igor, entrepreneur, former reporter, Ulyana's husband; E – Egor, a laboratory assistant at a provincial scientific centre. In the Murmansk region, Oleg and Roman test the latest weapon - a rifle with exceptional range and destructive power. The tests are successful, and Oleg is trying to interest the military in this weapon. Now one soldier with such a rifle is able to replace almost an entire army. Oleg turns to Igor and Ulyana, who help organise a meeting with the right people. As a result of the negotiations, it is possible to test weapons at a military training ground. After the tests, those who are interested in the invention break into Igor's flat. They are ready to do anything to get a new weapon, and the price of several lives does not seem so unacceptable to them...
