The video is about the world where almost everything is made of logos and characters of different brands. It starts with two Michelin cops chasing Ronald McDonald. The chase ends when an earthquakes hits the city and destroys everything.
I think this video is to show how our life is surrounded by so many different companies, and to show the power of brands. We can easily get impressions from just looking at the logos. I think they made Ronald McDonald as an antagonist to imply fast foods are bad for our bodies and McDonald is the biggest fast food company.
