A mature man Sergey Dolganov (V.Smirnov) is jack-of-all-trades, a man of generous nature and open heart, but at first sight looks like a looser. He has neither money, nor family, no constant job. He wanders about cities in search of a sole and unique girl, whom he would marry, make a family with, but in vain. And in all his free-will wanderings everywhere his fate casts him, he builds fountains not for money, but to bring people happiness. Once he happens to visit a steppe collective farm, where he is trying to build a fountain and where he meets the sole and unique. But a girl already has a boy-friend, and he has to do his best to conquer her love.
