The film follows Sharon McKendrick and Susan Evers, two identical twins who were separated at birth when their parents divorced. They meet by chance at a summer camp, discover their relationship, and plot to switch places in order to reunite their parents.
The success of the film rests almost entirely on the shoulders of a young Hayley Mills. In a technical marvel for its time, Mills plays both roles, interacting with herself seamlessly through the use of traveling mattes and split-screen photography. While the effects may seem quaint by modern standards, the charm of her performance—distinctly differentiating the refined Sharon from the tomboyish Susan—remains timeless.
