Kelley Quinn owns a bed-and-breakfast on Nantucket and is a proud father of four-Patrick, Shane, Ava, and Bart, all grown and living in varying states of disarray. As Christmas approaches, Kelley and his wife Mitzi anticipate a wonderful family reunion. But when Bart, the golden child and a recent Dartmouth graduate, announces that he has joined the Marines and is leaving for Afghanistan two days before Christmas, Mitzi is so distressed that she confesses to having an affair with a long-time guest at the Inn. As more secrets unravel and chaos ensues, it's up to Ava to piece together the holiday before everyone leaves-possibly forever.
