Eye of the Needle (movie)
The movie is about a deadly German Nazi spy named Henry Faber in the United Kingdom during World War II, who discovers vital information about the upcoming D-Day invasion and his attempt to return to Germany and tell Hitler about it, so that Nazi Germany stops the invasion from happening. While waiting for a German U-boat to pick him up and return to Germany with the top secret information, he is stranded with a family on the isolated (fictional) Storm Island, off the coast of Scotland. There he spends time with a young woman named Lucy, her bitter crippled husband David who was an RAF fighter pilot before his car accident and their toddler son Joe. He develops an intimate relationship with Lucy, but her husband is already suspicious of this new stranger.
