When Nikki discovers that her arch-nemesis, MacKenzie, has started writing a gossip column for the school newspaper, she's worried that she will share info on Nikki's crush, Brandon to the whole school.
To keep an eye on MacKenzie (and bonus: spend time with Brandon!) Nikki joins the newspaper and somehow ends up working as the advice columnist, Miss Know-It-All. At first it's fun to answer all the letters from the kids at school, but when her inbox is suddenly overflowing, Nikki feels in need of some help herself. Fortunately she has BFFs Chloe and Zoey on her side . . . and at her keyboard!
