 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.
