The Montgomerys--parents Charles and Judith and their three children: 15-year-old Alexander, 14-year-old Jennifer, and 8-year-old Emily--are spending Christmas at a new, isolated, state-of-the-art mountain cabin built by Charles' development company in upstate New York. Outwardly Charles built it so that they can spend time there to reconnect as a family, but they all know that he really built it to support the business. As a family they've long been unhappy; workaholic Charles is always concerned the company is close to folding, especially if he doesn't keep an eye on matters, while Judith feels like he treats their entire family as second priority to the work and the associated money and material wealth. They reach the cabin just before a major snowstorm hits the area. They receive a surprise knock on their door from the Tuckers--parents Joe and Amy and their children, 15-year-old Robbie and 14-year-old Lucie--whose van ran off the road on their way to a ski trip; they need shelter until the storm blows over. Unlike the Montgomerys, the Tuckers are a loving, happy, supportive family unit. The Montgomerys and Tuckers bond during their confined time together, but the Tuckers' presence might not be enough to show the Montgomerys what they must do to prevent the breakup of their family.
