The short version is that Emily goes to Paris and makes a lot of mistakes ... But then magically manages to fix them all in unrealistic ways and come out on top.

It's massive plot armor.

What makes it worse is that she's an American in France who doesn't speak French. This gives the impression that Americans are these magical people who can always come out on top eveb without speaking the local language (and conversely that the French are useless and old fashioned and backwards and can't fix anything themselves.)
