"The Brenner family is back, and their lives are more chaotic than ever. As Luke (Walker) is expecting twins, Taylor (Hynes) is debating a monumental job opportunity out of state, and Stephan (Campbell) attempts to plan for his upcoming nuptials, everyone's stress heightens when they learn their mom (Colin) has put their childhood home up for sale, marking their final Christmas in the Brenner house. With unexpected in-laws visiting, wild animals lurking in freshly cut Christmas trees, and a hesitant mall Santa, the boys will have their work cut out for them as the holiday begins to loom. As they navigate adulting at a level they have yet to reach, they must learn to once again lean on one another to rise to the needs of their growing family, conquer the newest challenges in their lives, and, most crucially, have the best Christmas EVER!"
