The series tells about the life of the business center "Nightingale", in which the private security company "Kedr" works. Lev Borisovich, the head of the PSC, is, as he himself believes, not only a guardian of material, but also moral and ethical values. In his subordination are four guards - Fedya, Tolya, Slava and newcomer Andrey. Andrey dreams of becoming a rock star, so he does not value the work of a security guard, but on the very first working day he meets Snezhana, a spa worker, and slowly gets drawn into the workplace of the business center. It is not an action movie with Jason Statham, it's just a story about a couple of days from the humble life of the guards of the Nightingale business center.

Rita, 33, works on television and gives the impression of a successful girl. However, in fact, there is an emptiness in her soul.

Not to mention the man — Rita's loneliness is brightened up only by a stuffed ferret, which she keeps in a place of honor in a rented apartment. The ruthless diagnosis that she learns about, it would seem, should finally kill all hopes of happiness. But it is he who becomes the starting point for her healing, getting rid of fears and finding true love.
