Phineas and Ferb plan their own New Year's Eve ball drop, complete with a customized multi-dimensional ball, while Candace makes it her resolution to refrain from busting her brothers before the clock hits midnight. Meanwhile, Doofenshmirtz uses a Resolution-Changer-inator in his tie as he continues the never-ending attempts to take over the Tri-State Area.

Candace challenges Buford to keep Phineas and Ferb's invention from disappearing so that she can sweep in and casually bust her brothers. Across town, Doofenshmirtz has had one too many lattes and is experiencing an extra burst of evil energy.
