Have you ever wondered what might have happened if... You had not taken the wrong turn and ended up finding your dream house. You hadn't gone on that blind date and met the love of your life. You hadn't stayed at the Blue Moon Inn. Is there really something special about the Blue Moon Inn? Four new guests are about to find out. Frank can't seem to get his ex-wife's voice out of his head. Kate wants nothing more in the world than to have a child and rescue her marriage from teetering on the brink of divorce. Damian is a U.S. Marine struggling to deal with his mother's death and to process the things he's seen in war. Maggie is a vivacious widow with a love for life, but she's about to discover that her husband wasn't the man she thought he was. Some of them have come to the inn looking to change their lives, others of them have stumbled upon it by chance, but none of them will be the same after their stay. Are these the kinds of coincidences that could only happen Once Inn a Blue Moon, or is there a larger fate at work?
