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.

The town of Elmo hopes for the best when they learn that Jack's life may be in danger. Eager to stay positive, a hopeful Marin focuses her energy on helping Cash through his illness; Patrick decides to take life by the horns and asks a young girl out; Annie discovers surprising news about Jerome's past life; and tensions arise between Sara and Pastor Eric when Eric's church group catches Sara in a compromising position.
