The cleaner

A man in a white shirt sits in front of a microphone, smiling and reacting to a video on the right side of the screen. The video shows a young boy in a black t-shirt with Russian text, standing in a kitchen and singing or shouting with his mouth open, then turning and walking away from the camera down a hallway. The scene cuts back to the boy in the kitchen, still singing, before the video ends with a shot of a pair of shoes on a wooden floor.
