S2, E24: In the season finale, on Jack's last case before he moves to Chicago, the team searches for a billionaire's estranged wife and their two children after the yacht they were last seen boarding is soon found adrift in New York Harbor--with only its dead captain aboard. Jack becomes suspicious of the steely and sarcastic billionaire Ben Palmer (Jon Tenney), but additional suspects begin to surface as well. Palmer receives a cryptic ransom call from a man demanding to receive what belongs to him in exchange for returning Palmer's family alive. The team and Palmer have only eight hours to figure out what the kidnapper wants. Meanwhile, Jack and his team prepare for Jack's move to Chicago, and Vivian waits to hear if she'll be promoted to replace him.
