In this remake of the eponymous 1961 film, identical twins Hallie and Annie (Lindsay Lohan) are separated at birth and each raised by one of their biological parents after their divorce. Raised on opposite sides of the Atlantic, American Hallie and British Annie meet by happenstance at a summer camp. When the two realize that they are indeed twins, they hatch a plan to swap places with one another, and reunite their long separated parents (Dennis Quaid, Natasha Richardson).
