Dead Boyz Can't Fly(1992)

An outrage in America.

Buzz shows his artwork to Norman at the employment agency. Norman laughs in his face. Buzz takes this personally and later returns to the office building with his friends Goose and Jo Jo. They systematically terrorize the people in different offices on the 13th floor, with only a few grizzled Vietnam veterans and a suicidal lawyer to try and stop them.
