Outside the window is a rainy London autumn. High ceilings, dank walls. Bella's lonely woman's apartment. Sometimes her look famous personages, courageous generals, Eastern beauties and American billionaires, but more often she has to spend days and nights in the society of talkative maids. Memories from the past, beautiful life ghosts roam around, and bright flashes come to life in the stories of the mistress. But more and more often the evening turns into a struggle with a terrible lingering loneliness. And suddenly, the bell rang. Visit the young man as an opportunity of real life, as a chance to start again, as a new motif in the melody of the old tango.
