For the first time in Married at First Sight history, the experts sit down with each spouse to find out: what will it take for these couples to say yes on decision day? And, if they feel there is no hope in sight, each individual will have the option to get out! With only four weeks left, who will stay committed to their spouse? And who will get off the marriage train early?

With only one week until decision day, all four couples head up to the mountains for a romantic couples retreat. Will the fresh air be what they need to deepen their bonds, or will this time together reveal who's committed to their marriage, and who isn't?
