Freaky Friday
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 (Julie Gonzalo), 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 band audition, 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 the school prom, 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 work, Anna counsels the patients with some difficulty and then gives her mother's body a makeover, including new clothes, a new haircut, and an ear piercing. At lunch, the two go to the restaurant and talk to Pei-Pei, the daughter of the woman that gave them the fortune cookies. Furious at her mother's meddling but unable to directly help them, Pei-Pei advises them to read the fortunes in the cookies, as when the fortunes come true, they will swap back. The fortunes tell that "when what you gain is what you lack, then selfless love will change you back", leaving them just as confused.
In the afternoon, Anna attends Harry's parent-teacher conference, where she learns that he secretly admires his sister greatly, but provoked fights so that she'd pay attention to him. When Tess took Anna's test, Stacey made it look like Tess was cheating. Tess is able to finish the test later with the help of Jake, an older student that Anna had a crush on (she also gets revenge on Stacey by erasing all of Stacey's answers and replacing them with "I'm Stupid!").
Meanwhile, Ryan surprises "Tess" with an interview on a talk show to discuss her new psychology book. Anna is unable to discuss the meaning of the book, which she hasn't read, so she improvizes by turning the show into a wild romp. Afterwards, Anna sees Jake at a coffee shop and bonds with him over similar musical interests. Jake then begins to fall for "Tess", when he notices all the characteristics he likes about Anna.
At the wedding rehearsal that evening, Anna's bandmates come to try to convince "Anna" to go to the audition. Ryan gives her permission and tells "Tess" that he wanted Anna to accept him into the family on her own. Seeing Ryan in a new light, Anna leaves to watch her band perform. At the audition, Tess is unable to play the guitar so Anna unplugs it and plays another guitar backstage. For the first time, Tess realizes how exciting it is to be on stage and why Anna loves the rock band.
Back at the wedding, Tess asks Anna to have Ryan postpone the wedding, so that Anna won't have to go through marrying him in her mother's body. Instead, Anna proposes a toast where she accepts Ryan. There is a second earthquake that everyone feels (probably because they were all in the same room with Anna and Tess at the time) and Anna and Tess switch back into their own bodies.
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.
