Having learned from the doctors that he has only a few weeks to live, Nikita makes the courageous decision to transfer his family and work to decent hands. An employee of the Ministry of Emergency Situations named Ilya becomes a candidate for a replacement, a decent man all around. Nikita makes every effort to “introduce” Ilya as soon as possible into his life and unexpectedly succeeds in this. Soon, Ilya becomes an excellent father for Nikita's children, an indispensable employee at the clinic and, most importantly, a very appealing man for Masha, Nikita's beautiful wife. However, the real test of this is only beginning, because Nikita soon realizes that the doctors were wrong, and in fact he will not die at all in the near future. Now he has to win back his place in the family and at work, and it turns out to be much more difficult than it seems at first glance.
