Dirección: David Swift
Dos niñas gemelas, separadas por el divorcio de sus padres, se encuentran en un campamento de verano. Inicialmente no se percatan de su origen común, pero tras ser ambas castigadas a compartir la misma habitación, se dan cuenta de que son gemelas. Ahí también se prometen un objetivo: volver a juntar a sus padres. Para ello deciden intercambiarse.
