Miss Fanouria Kalafati, also known as Ritsa (Sappho Notara), is a very intelligent doorwoman, to whom everyone runs to tell them the truth and advise them on their love affairs. Of course, she interferes in their lives at every opportunity, as in the case of a singer, Zozefina, who sets her up with a middle-aged earner, Michalakis, in order to make her suitor, Sakis, jealous and stop postponing the wedding. When she realizes that her niece is in love with a young man, she rushes to grant them her wish, while she herself still loves Antonis, her youthful love who had emigrated to Australia. A lottery ticket, given to her by Michalakis, makes her rich overnight, so she buys the penthouse of the apartment building and houses her love, since Antonis returned from Australia the same way he left, that is, penniless.
