Nine-year-old Emma O'Fallon finds herself in increasing difficulties as her complicated efforts to break up the growing attachment between Annie, the Irish nanny, and Bo, her boyfriend, cause chaos on a family camping trip and her own relationship with her best friend Luisa seems to be going from bad to worse.

One big stupid dilemma --Tim helps -- Emma has a better plan -- Best friends trouble -- Emma breaks a big, big rule -- Annie to the rescue -- Marmaduke is gone! -- Going camping -- McClain tags along -- A truly brilliant plan -- A bear comes to call -- Everything stinks -- Best friends again -- Annie's big day -- Emma ruins it -- Emma figures things out -- A (mostly) happy ending.
