I Know Where I'm Going! is a 1945 romance film by the British-based film-makers Michael Powell and Emeric Pressburger. It stars Wendy Hiller and Roger Livesey, and features Pamela Brown, Finlay Currie and Petula Clark in her fourth film appearance. Joan Webster (Wendy Hiller) is a young middle-class Englishwoman with an ambitious, independent spirit. She knows where she's going, or she thinks she does. She travels from her home in Manchester to the Hebrides to marry Sir Robert Bellinger, a very wealthy, much older industrialist, on the Isle of Kiloran. When bad weather postpones the final leg of her journey—a boat trip to Kiloran—she is forced to wait it out on the Isle of Mull, among a community of people whose values are quite different from hers. There she meets Torquil MacNeil (Roger Livesey), a naval officer trying to go home to Kiloran for some shore leave. They spend the night in the nearby home of Torquil's friend, Catriona Potts (Pamela Brown). The next day, on their way to catch a bus into town, they come upon the ruins of Moy Castle. Joan wants to take a look inside, but Torquil refuses to go in.
