Fyodor Sadovsky, 35, is a delicate businessman with an impeccable reputation. He managed to turn his obsession with cleanliness into a source of income by opening his own cleaning company. However, even a successful business does not help Fyodor to get out of the shadow of his father, a Soviet cosmonaut, in whose honor a memorial plaque is installed on the house in the center of Moscow. There has been no place for new people in his life for a long time, much less exploits. His life schedule is perfectly formed — on Wednesdays his mother comes to visit him, on Saturdays his only friend Borya.
