Masha, Masha…

Four people are in a room with a large window showing city lights at dusk; two women stand on the left, one in a striped shirt and white jacket, the other in a light-colored dress, while two men in light-colored clothing are bent over the window sill on the right. The woman in the dress stands up, holds a book above her head, and moves it back and forth in a rhythmic motion while the woman in the striped shirt claps and laughs, then the woman in the dress bends back down to the window.
