Ann is a 25 years old girl who smokes over a pack a day. Throughout all the clip she is constantly taking drags like she's never satisfied enough, holding very frequently the smoke in her lungs to make the most out of her cigarette. This girl also has a terrible vice: she likes sucking the cigarette down to the filter as you can see especially in the first scene where the filter starts burning in flames, and in the last scene where she smokes a part of the filter.
In the video Ann smokes 3 cigarettes in 3 different scenes and different outfits, always smoking each cigarette down to the filter until nothing more is left. There is a little interview about how many cigarettes she smokes a day and when she started smoking (very young...), but mainly this girl is only focused on her pleasure tool, having not much time for words.
