It's about a guy who eats McDonalds for 30 days. He had to eat everything on the menu at least once. If the people at the front asked him if he wanted to super size it, he would HAVE to!
A man named Morgan embarked on a 1 month Mcdonalds binge. The movie is all about how he gained a massive amount of weight and he was sick from eating McDonalds too much.
