Phineas and Ferb: Summer Belongs to You!

Phineas and Ferb, bored after a busy summer, decide to travel around the world at the speed of the Earth's rotation to craft the biggest, longest summer day. They depart from Danville to begin their global sprint.

In Tokyo, Doofenshmirtz accompanies Vanessa as she sees his plan to ruin the International Good Guy Convention with a giant water balloon and to frame Major Monogram. Distressed by this, Vanessa decides to leave for Paris.

Perry the Platypus learns Monogram's whereabouts after Carl warns him of a suspicious note sent to the O.W.C.A. headquarters. This information sets up Perry's cross-organization pursuit.

In Tokyo, the group meets Stacy Hirano and even encounters Stacy's cousins while scavenging vegetable oil to fuel their mission. The city becomes a hub of odd allies and improvised resources.

Vanessa is knocked off the Tokyo Tower by Perry’s intervention and ends up joining the adventure. Doofenshmirtz abandons his own rescue plan and instead convinces Perry and Monogram to help him reach her aboard a hovercar.

Doofenshmirtz, Perry, and Monogram team up to rescue Vanessa aboard Perry's platypus-shaped hovercar. The unlikely alliance shifts Monogram's priorities but advances the rescue mission.

The group crash-lands on the Indian portion of the Himalayas and meets Baljeet Tjinder and his grand-uncle Sabu at a rubber band factory. Sabu's song Rubber Bands inspires a playful idea: power the plane with a bouncy rubber ball attached to its underside.

With the rubber-ball power concept, they plan a global hop back toward Paris and home, punctuated by the chorus of Bouncin' Around the World. The journey becomes a literal and musical adventure across continents.

In Paris, Candace spots Jeremy Johnson in a crowd and pulls away from him. Isabella Garcia-Shapiro grows upset because Phineas is so focused on perfecting the craft. Ferb suggests Vanessa repair her relationship with her father by meeting him halfway and socializing more.

Doofenshmirtz, Perry, and Monogram converge to rescue Vanessa, and Doofenshmirtz feels genuine pride in his daughter's rare act of villainy.

Back on the island, Phineas, after a desperate attempt to find a way off, sits with Isabella as the sun sinks. Inspired, he uses Ferb's giant map to create a massive paper airplane.

The group launches the enormous paper airplane and rides it back toward Danville. Buford returns everyone's bikes, and the crew vaults a road ditch with a ramp, arriving home with one minute to spare.

They arrive back in Danville as the neighborhood recovers. The parents return and the group belts out Summer Belongs to You, while Candace watches with quiet satisfaction.

In the Paris finale, Jeremy returns a bit earlier and kisses Candace, declaring her his girlfriend. The moment caps off their evolving relationship.

Perry is last seen dating a woman at a Paris restaurant, hinting at further adventures to come. The teaser sets up future escapades for Perry and his human allies.
