Parker Cruse despises cheaters. It might have something to do with her boyfriend sleeping with her twin sister. After a wedding day prank involving a strong laxative, that ends the already severed relationship between the twins, Parker decides to grow up and act twenty-six.

Step One: Move out of her parents' house.

Step Two: Find a job. Opportunity strikes when she meets her new neighbor, Gus Westman. He's an electrician with Iowa farm-boy values and a gift for saying her name like it's a dirty word. He also has a wife. Sabrina Westman, head of a successful engineering firm, hires Parker as her personal assistant. Driven to be the best assistant ever, Parker vows to stay focused, walk the dog, go to the dry cleaners, and not kiss Gus-again.

Step Three: Don't judge.

Step Four: Remember- when life happens, it does it in a heartbeat.
