Plot Synopsis

Ingenious Phineas Flynn and his resourceful stepbrother, Ferb Fletcher, happily set out to conquer boredom and make every day of their 104-day summer vacation count. Among their fun-filled projects are building a full-scale roller coaster, creating a new season called "swinter," becoming overnight pop music sensations, building a backyard beach complete with a surf competition, and traveling back in time to the Jurassic period. Throughout the escapades, they're accompanied by Perry the Platypus, their seemingly mindless family pet who, unbeknownst to all, has a double life as suave secret Agent P, deftly battling the evil Dr. Doofenshmirtz to save the world. Meanwhile, older sister Candace is aghast at her brothers' bold antics and makes it her life's work to tattle on them to Mom and Dad, though somehow she can never seem to catch them red-handed.

On Tuesday, June 9, 2015 at 8pm ET/PT, Disney XD started a 73-hour marathon of encore episodes of PHINEAS AND FERB, in anticipation of the series finale on Friday, June 12, 2015 at 9pm ET/PT on both Disney XD and Disney Channel. In the final episode, "Last Day of Summer," Candace has one final chance to bust her brothers before the summer season comes to a close. As usual, her efforts are thwarted until she gets the chance to redo the day with Dr. Doofenshmirtz's newest machine: the Do-Over-Inator. Suddenly everything turns topsy-turvy and as the dastardly device rips into the space-time continuum, the days get shorter and Phineas and Ferb disappear entirely.

On Monday, November 9, 2015 from 7:30-8:30pm ET/PT, Disney XD premiered a one-hour special, "The O.W.C.A. Files," of PHINEAS AND FERB. This 60-minute standalone special focuses on the organization's best secret agent, Agent P (also known as Perry the Platypus), and his fellow animal agents. When an evil mastermind from Major Monogram's past, Professor Parenthesis, launches an attack on The O.W.C.A. by incapacitating the animal agents with robotic fleas, only Agent P and his agent trainees can save the day. Guest starring are Paul Reubens as Professor Parenthesis, JK Simmons as Napoleon, Josh Gad as Wendell and Stephen Root as Floyd.
