Rebecca Bunch is a successful, driven, and possibly crazy young woman who impulsively gives up everything - her partnership at a prestigious law firm and her upscale apartment in Manhattan - in a desperate attempt to find love and happiness in that exotic hotbed of romance and adventure: suburban West Covina, Calif.

In an attempt to get closer to Josh, Rebecca throws a housewarming party despite her lack of social connections in West Covina and a childhood fear of hosting parties. When Paula finally convinces her, the party turns out to be nothing like they anticipated.
