A man in a suit stands centered within a collage of rectangular frames, surrounded by repeated close-ups of a smiling mouth, as the frames shift and rearrange around him. The scene cuts to a man with a mustache singing into a vintage microphone, his arms outstretched, before the collage reconfigures to show him in the center, flanked by images of a woman and a man playing a double bass. The sequence continues with a close-up of the mustached man's mouth, then his face as he sings, and finally a shot of him centered between two images of a man playing a double bass, all within the shifting grid
