A determined young Englishwoman sets out to accomplish her goals even at the risk of her heart.

Joan Webster is a very modern woman (in the 1940's), "She knows where she's going", she has her life carefully planned out from a very young age. She gets engaged to a rich industrialist who has taken a lease on an island in the Hebrides, so she travels up to Scotland to marry him. However, in the Western Isles, life beats to a different drum. A storm prevents her immediate journey to the island so she stays for a while with some of the locals including a young Naval officer, Torquil MacNeil, who turns out to be the local clan head and the true owner of the island. The magic of the local land, it's history and the eccentric people she meets begin to have an effect on Joan and she wonders ... does she really "Know where she's going".
