As the episode begins, Phineas and Ferb are excitedly discussing what to do for their Christmas break. Their sister Candace, however, is less enthused, dreading the boredom that often comes with summer vacation. Undeterred, Phineas and Ferb soon begin work on their latest project, which is to build the world's largest Christmas tree.

Using their usual madcap inventiveness, the boys gather materials from around the neighborhood and beyond to construct the massive tree, complete with flashing lights and a working train set encircling its base. But as the tree grows larger, Candace becomes increasingly worried that their mother will see it and punish them all for their elaborate antics.

Candace, fearing the worst, worries that their mother will notice the tree and punish them all. But just as they finish the tree, a sudden gust of wind blows it over, sending all their hard work crashing to the ground. Candace, relieved that they won't be punished after all, even helps the boys clean up the mess.

As the episode comes to a close, the family gathers around the fireplace for a cozy Christmas evening together, with Phineas and Ferb contentedly reflecting on their latest successful project.
