The TV advert (includes print and outdoor ads), which is due to air for the first time today, is expected to see Willis adopt a “stereotypical celebrity persona” as he attacks the headquarters of a presumably rival broadband ISP (BT or Virgin Media etc. – we don’t know).
Apparently Willis’s reason for doing this is because he has just exceeded the download limit of his package while streaming an online movie and doesn’t like the suggestion of being told to watch it in a lower quality instead. So at least the plot of this advert is no worse than that of Hudson Hawk or Die Hard 4.
