Dance in nothing

The daily life of different people, a pregnant woman giving birth, a man eating, an old man flipping through his memory album, a musician playing the violin, and other people doing their daily work, but they are doing nothing. The woman gives birth but no child is born, the man eats but eats nothing, there are no photos in the old man's diary but he looks at the empty photos, the musician is playing but no sound comes from the accordion. At the end, a woman sitting on a chair cuts a vein in her hand and dies slowly.
