Joanie is Captain of her Soccer Team, and a girl who knows her own mind. She lives with her mother, newly married to a nice guy with a dorky name and his son named Jeff.
Jeff wants to learn to play guitar, but he's really, really bad at it. He's determined to learn, he plays until his fingers bleed, which is freaking his step-mother out. Another part of the problem is that their little house is full of stuff. Nobody is happy living in a house full of boxes.
Joanie has decided it's time to de-clutter the house and stop Martha from picking on Jeff. She might be his step-sister, but she's not about to be his wicked step-sister.
