The story starts in Boulder, Colorado with four best friends — Harper Waddle, Sophie Bushell, Becca Winsberg, and Kate Foster — who have finished high school and are supposed to be going to college.

Kate's 14-year-old sister, Habiba (usually called "Beebs"), who was adopted from Ethiopia, is also a big part of the story.

She lies and tells them she rejected NYU and is going to pursue her dream of writing the next Great American Novel.

Sophie goes to Los Angeles to become an actress, staying at a wealthy family friends' guest house.

When at a party Sam took her to, she bumps into famous actor, Trey Benson, and finds out he is starring in the movie she is in.

They start to date and, although he treats her without respect, he pretends to be a complete gentleman after Sophie confronts him.

Before she left, Harper, Sophie, Becca, and Habiba gave her a list of things to do in Paris and all over Europe.

They find each other again and they finish everything on her list of dares together but have to say goodbye when he has to leave for Stockholm University.

A guy she has a crush on, Stuart, carries Isabelle to the nurse, where she tells her everything that happened that night.

The sequel to Bass Ackwards and Belly Up, Footfree and Fancyloose, was released April 1, 2009.
