Finn and Layla are young, in love, and on vacation. They're driving along the highway when Finn decides to stop at a service station to use the restroom. He hops out of the car, locks the doors behind him, and goes inside. When he returns Layla is gone, never to be seen again. That is the story Finn told to the police. But it is not the whole story. Ten years later Finn is engaged to Layla's sister, Ellen. Their shared grief over what happened to Layla drew them close and now they intend to remain together.
