Inspired by the true events of a Korean newlywed couple being kidnapped for their organs on a ferry in 2009,
The movie kicks off with a young couple Sang-Ho (Choi Daniel) and Chae-hee (Jung Ji-yoon) excitedly boarding a China-bound ferry for their vacation. After leaving his wife for a few moments, Sang-ho discovers that his wife has disappeared without a trace from the ferry, almost as if she was never to have gotten on board to begin with. Meanwhile Young-kyu (Im Chang-jung) the head of the organ trafficking operation is given an offer he cannot refuse as a last job before leaving this line of work, only to discover that his target is Chae-hee, putting him in a moral dilemma throughout the film.
