The wide generation gap between Tess Coleman (Jamie Lee Curtis) and her teenage daughter Anna (Lindsay Lohan) is more than evident. They simply cannot understand each other's preferences. On a Thursday night they have a big argument in a Chinese restaurant. Both receive a fortune cookie each from the restaurant owner's mother which causes them to switch bodies next day. As they adjust with their new personalities, they begin to understand each other more and eventually it's the mutual self-respect that sorts the things out.
