25-year-old Mel Parker has a few tiny problems:

* Her job is terrible
* She's been dumped yet again (and her ex is now her boss)
* Her parents think she's a loser compared to her perfect younger sister
* All her efforts to improve her life seem doomed to failure
* There just isn't enough chocolate in the world to make up for the above.

The best thing in her life has always been her best friend Will, who has seen her through every crisis from lost toys to pregnancy scares. But his girlfriend (who's prettier, better-dressed, more successful and secretly evil) is determined to replace Mel as the woman in his life and how is Mel supposed to compete?

And what do you do when you've pretty much given up on your own life? You help others, of course! Whether they like it or not.

After all, what's the worst that could happen?
