Jack's ship has gone down in the Bering Sea, but Marin doesn't know this and is upset by his lack of communication. And when she finds herself being romantically pursued by her publisher, Stuart, she must decide whether or not the possibility of Jack is worth waiting for. To complicate matters further, Patrick, still suffering from amnesia, also takes an interest in Marin -- which proves very upsetting for Annie. Meanwhile, on a trip to a snowplow convention, newlyweds Jane and Sam come up with a unique living arrangement; Sara and Eric take a step forward in their relationship, which also means a step back; and, adrift at sea, Jack must make a very tough decision to save his life and Julia's.
