Summary
When a mysterious rift threatens the fabric of time itself, Perry the Platypus is critically injured while protecting both the Tri-State Area and his secret identity. As OWCA scrambles to stabilize him and contain growing dimensional chaos, Phineas and Ferb struggle with their pet’s sudden disappearance. While their summer slows to a standstill, Stacey—now reluctantly pulled into OWCA as a temporary operative—must keep Perry’s secret and support her heartbroken best friend Candace, who begins to unravel under the pressure of watching her brothers lose their spark.
Meanwhile, Doofenshmirtz confronts his past while attempting to help the former-nemesis who has helped him countless times. With the help of the 2nd Dimension Resistance crew, OWCA races to uncover the truth behind the worsening rift crisis and save not only Perry but the entire Tri-State Area.
As timelines fray and bonds are tested, Perry must fight to recover, protect the boys he loves, and remind everyone what truly holds the multiverse together: loyalty, found family, and the quiet strength of a platypus who never gives up.

Summary
Believing that everything in his life could be fixed if he had only become class president in High School, Heinz Doofenshmirtz uses his past invention, the De-Age-inator, to become 18 years old again and quickly enrolls in Danville High. However, in the high school political arena, Doof faces fierce competition from his opponent, a girl named Candace Flynn, whom smells something fishy about the new "exchange student" and soon sets out to bust him!
When the two are paired as lab partners, though, their mutual understanding soon works against them and turns their fierce rivalry into something neither of them expected.
Heinz now has to ask himself if he's evil enough to take his daughter's friend to the prom before taking over the Tri-State area, while Candace has to answer, once she gets the evidence she craved, if she's prepared to bust someone she's fallen in love with? And if she'll really be okay this time when everything disappears.
It seems neither teenagehood nor middle agedness is all it's cracked up to be.
