Charlie and Louise

Wolf and Sabine Palfy got divorced 10 years ago; Wolf took custody of their daughter Charlie while Sabine took custody of Charlie's twin Louise. For a whole decade, Charlie and Louise knew absolutely nothing about each other until they met by chance at boarding school in Scotland. At first they cannot stand each other, but after a while they start gathering information about their origins. When they realize their relationship, they plot to bring their parents back together by Charlie visiting their mother pretending to be Louise, while Louise goes to their father pretending to be Charlie. Can they reunite their family?
