Anna Coleman (Lindsay Lohan) is a common teenager who constantly rebels against her stodgy mother Tess (Jamie Lee Curtis) and annoying younger brother Harry (Ryan Malgarini). Sources of irritation include a rock band Anna’s in, which her mother dislikes, and Tess’s upcoming wedding to a man named Ryan (Mark Harmon), which Anna is emotionally not ready for. Also contributing to Anna’s irritation is her enemy, Stacey Hinkhouse, the “insane pyscho freak” who never seems to stop torturing her, and Anna’s English teacher, Mr. Bates, who gives her an F on every assignment, no matter how hard she tries. Her love interest is Jake (Chad Michael Murray). When the family, along with Ryan and Anna’s grandfather (Harold Gould), eat out in a Chinese restaurant, Anna and Tess quickly start into a fight again: Anna wishes to participate with the rest of her band in a talent show, however the show is the same night as Tess’s wedding rehearsal. Hearing the argument, an elderly Chinese woman offers Anna and Tess both fortune cookies. Upon opening them, there is a short earthquake which only the pair feel. The next day, Tess wakes up and discovers that she is in Anna’s body. Likewise, Anna is in her mother’s body. Confused, they decide to go back to the restaurant at lunch to find out what happened. Since Anna has an important test and Tess must go to work (as a psychologist, some of the patients are dependent on her), the two are forced into each others roles. At school, Tess is given a bad grade from Mr. Bates and realizes that he had asked her when they were younger to a dance, which she refused and now he was taking it out on Anna. Tess confronts Mr. Bates in front of both of Anna’s friends, humiliating him.
At the wedding the next day, Anna’s band performs and Anna gets a chance to dance with (and kiss) Jake. Pei-Pei’s mother notices Harry and his grandfather fighting and offers them fortune cookies…which Pei-Pei manages, via tackle, to retrieve before they are opened.
