In this charming family comedy, two identical twins, separated at birth, accidentally meet at a summer camp. Annie, the sophisticated and educated daughter of a wealthy couple from London, and Hallie, the adventurous and mischievous girl of a widower in California, soon discover that they have more in common than just their appearance. Upon learning of each other's existence, they decide to swap lives for a while: Annie will travel to the sunny California coast, while Hallie heads to her sister's posh life in London.
As the twins try to adapt to their new lives, each faces her own challenges: Annie must deal with the eccentricities of Hallie's family, while Hallie tries not to draw attention in a much more formal environment than she is used to. As the two girls strive to fit in and make the most of their new surroundings, they begin to hatch a clever plan: to reunite their parents, separated by time and circumstances, and prove that true love never dies.
Amid mischief, misunderstandings, and tender moments of connection, these twins will show that family isn't always about blood, and that sometimes, a little magic and creativity can change the course of lives. With laughter, emotions, and a touch of romance, this story resonates in the hearts of both young and old.
