In a ground floor apartment a middle-aged woman sings a baby to sleep. Random street images that penetrate this intensely private domain like reflections in a mirror attract her attention and cause her to start spinning a fictional scenario around an impending arrival, which she both longs for and dreads. Haunted by this pervading sense of expectation she starts making preparations to receive the visitor while the initial tenderness and devotion of the cradlesong is gradually supplanted by the narcissism of an introverted, delirious monologue.
