He's rapping lyrics while moving around a bit. Basically doing his own thing and minding his own busines.
Then comes a guy with a knife. Cut to a soundstage in black and white: They tussle with him until P is cut up and stabbed .... but he never passes out, just hurt. Cut back to the location with P limping off.
P is approached by guys with bats...Cut to the sound stage: they take head shot after head shot with bats but nothing keeps him down ... Cut back to the location with P running away.
P arrives to a powerful man with a gun. Cut back to the soundstage: The man shoots repeatedly. Bullets hit P in slow mo but he keeps walking. (all on the sound stage)
Cut back to the location. P, stabbed, beaten and shot, sits on the stairs where he started...rolls and lights up a blunt.
