I'm beautiful

A man in a grey shirt and glasses looks up in alarm as his hand is held in front of his face, while a thin object, possibly a knife, is held vertically near his face. The scene then cuts to a man in a light blue shirt outside, who is violently shaking a black bucket, causing sparks and smoke to erupt from it. The scene changes again to a bathroom where a man in striped underwear is leaning over a bathtub, repeatedly dunking another man's head into the water, while a black bucket is placed on the edge of the tub.
