When medieval historian Meredith Foster finds a man in a leather tunic roasting a rabbit in her fireplace. She thinks it's some kind of elaborate joke. But as she teaches him to eat spaghetti and use a computer, Meredith comes to realize that he knows much about the tenth century and nothing about the 20th. Should she surrender to the fantasy that Geirolf Ericsson really is a Viking from 1,000 years ago? And as he helps her fulfill her grandfather's dream of re-creating a Viking ship, he awakens her to dreams of her own.
