A man in a dark suit and patterned tie sits at a table, then the scene cuts to a man with chaotic makeup and a wide, unsettling grin, who leans forward and laughs maniacally. The sequence continues with close-ups of his face, showing his intense expression and smeared makeup, before he is seen standing in a dimly lit urban environment, then leaning in close to a woman holding a knife to his face.
