Episode Summary
|From starwars.com:

The adventuring stars of Disney's hit animated series Phineas and Ferb are heading to a galaxy far, far away: A special Star Wars-themed episode of the musical-comedy series is currently in production, announced July 19, 2013 by show creators and executive producers Dan Povenmire and Jeff "Swampy" Marsh at Comic-Con International in San Diego. The one hour event episode will premiere next year on Disney Channel and Disney XD, placing the characters of Phineas and Ferb in the same space and time as the world of Star Wars.

Povenmire said, "May The 'Ferb' Be With You and with all of us who for decades have dreamt of a chance to work with the great characters and stories of Star Wars."

The episode's story begins a long time ago, in a galaxy far, far away -- in summer. Phineas and Ferb are living happily on Tatooine, just one moisture farm over from Luke Skywalker. They love simply hanging out and creating new adventures under the twin suns, however, they find themselves thrust into a global rebellion when the plans for blowing up the Death Star accidentally fall into their hands.

Now that fate has suddenly pulled them into the fight for freedom, they must go in search of a pilot who can take them to the Rebels so they can hand over the plans. Complicating matters, Candace -- the boys' sister -- has a Stormtrooper-like intent on "busting rebels" who chase Phineas and Ferb across the galaxy in hopes of retrieving the Death Star plans.

Meanwhile, back on the Death Star, Dr. Darth Enshmirtz, a low level Darth, has created a Force-powered "Sith-inator" that he plans to use against the Rebel Alliance. Agent P, working undercover for the Rebellion, is dispatched to stop him, but quickly gets trapped in carbonite. Then, things take a startling turn when Ferb is accidentally hit by the full blast of Dr. Darth Enschmirtz's "inator" and becomes...an evil Sith.
