There is a man nodding in the first frame.  The video movies to the man putting up the wall paper by first measuring it out, lining up the pattern and putting it up on the wall.  He then unscrews a light switch and pulls it out just a little, making some slits in the fabric or paper, then putting the light switch back over the new wall paper.  The camera shows wall paper in a finished room, going over different rooms with different wall papers.  The man is later seen measuring and marking the wall, rolling out more wall paper and putting it up on the wall.  Then it shows two tables that look like they have also been wall papered.
