Plot
To celebrate the anniversary of Perry becoming their pet, Phineas and Ferb create an enormous shuttlecock to play giant badminton. When Perry's hovercraft accidentally collides with their shuttlecock, the boys crash into Dr. Doofenshmirtz's lab and destroy his "Other-Dimension-inator", which creates portals to parallel dimensions. Intrigued, the two help Doofenshmirtz rebuild the machine. Perry arrives to stop Doofenshmirtz, but unwilling to reveal his secret identity to the boys, reverts to pet mode and is unable to stop them from helping Doofenshmirtz.

The group travels to an alternate dimension where an evil Doofenshmirtz rules the Tri-State Area with his army of Norm-Bots. The second Perry (known as Platyborg) was converted into an evil cyborg by Doofenshmirtz-2 and programmed to serve as his second-in-command. Doofenshmirtz-2 orders Platyborg to attack the boys, forcing Perry to reveal his secret identity, much to the boys' shock. Perry and the boys escape, but Phineas is angry with Perry for his long term deception.

With the remote for their portal broken, the boys seek out their alternate selves, who have grown up without knowing about summer. Doofenshmirtz-2 decides to use the Other-Dimension-inator to invade the original Tri-State Area. In order to keep Perry off track, Doofenshmirtz-2 announces he will spare Phineas and Ferb if Perry surrenders. Perry agrees to the deal, but before he leaves he is told by an angry Phineas he is no longer their pet. When Doofenshmirtz-2 learns that only the boys can fix the Other-Dimension-inator, he backs down on the deal.

Phineas and Ferb ask the alternate Isabella for help and find that she and alternate versions of Baljeet, Buford, and the Fireside Girls are part of the resistance movement, led by the alternate Candace. Baljeet-2 is able to open the portal to the original dimension, but upon learning about Perry's capture, Phineas and Ferb decide to rescue Perry before they can leave. In the original dimension, Candace spots the portal and jumps through, causing it to close.

The kids set off to rescue Perry, but are trapped by Doofenshmirtz-2 and his forces. They escape with Perry when he provides a distraction, but during the chase, Platyborg disables one of the mine carts, slowing them down. Unwilling to endanger her brothers, Candance-2 abandons Phineas, Ferb, Candace, and Perry. The boys refuse to fix the machine, but inadvertently remind Doofenshmirtz how they fixed his machine by removing the self-destruct button. After Doofenshmirtz powers up the machine, Doofenshmirtz-2 orders Phineas, Ferb, Candace, and Perry to be fed to a monster called the Goozim; when Doofenshmirtz annoys him again, Doofenshmirtz-2 orders him to be fed as well.

Before the five can be eaten, Candace-2 rescues them and gives them the remote, allowing Phineas, Ferb, Candace, Perry, and Doofenshmirtz to travel through other dimensions until they reach their home dimension. Despite this, Candace-2 is captured by the Norm-Bots. Doofenshmirtz-2 arrives at the first dimension and releases the Norm-Bots into Danville. Perry gives Phineas and Ferb the locket off his collar, which leads them to Perry's lair. Inside, they find replicas of all their previous inventions. With the help of their friends, the children of Danville, and the O.W.C.A. agents, Phineas and Ferb use the inventions to defeat the Norm-Bots, while Candace-2 is freed by Phineas-2, Ferb-2, and Jeremy-2, and Perry defeats Platyborg. Doofenshmirtz arrives and gives Doofenshmirtz-2 a toy train that he lost when he was a kid, which was the reason for his turn to evil. His tragic backstory resolved, Doofenshmirtz-2 self-destructs his Norm-Bots and returns to his own dimension, being arrested upon arrival.

Platyborg, freed from his evil programming, reverts to his normal self, and Phineas-2 and Ferb-2 take him home. The kids are distraught to learn that Perry will be relocated since his cover is blown, but Carl proposes using Doofenshmirtz's Amnesia-inator to erase the kids and their friends' memories so they can keep Perry. Before they forget, Phineas and Ferb say their goodbyes to Perry, and Isabella seizes the opportunity to kiss Phineas. Perry enters his lair and uploads photos from the day onto his computer.
