Cate is the daughter of First Officer Will Murdoch, on her way to fulfill her duties as a socialite, inherited by her wealthy mother. She thinks she has a dull, loveless life ahead until she meets Sixth Officer James Moody, whom her father has forbidden her to see. Will they be able to be together or will fate ultimately pull them apart?
