Phineas and Ferb build a gondola ride for Jeremy to impress Candace. Meanwhile, Doofenshmirtz plans to steal all the Valentine's Day presents and create a new holiday, "Broken-Heart Day".
On Valentine's Day, Candace, anticipates going to the dance with Jeremy and all of the presents he will give her. As Phineas and Ferb wonder what to do, Jeremy asks them for help- all of the Valentine's Day presents have been stolen! Meanwhile, Perry the Platypus runs off to receive his secret mission from Major Monogram: recover the Valentine's Day presents that have been stolen by Dr. Doofenshmirtz.
Phineas, Ferb, Jeremy, and Isabella begin work on their secret project for Candace as Perry makes his way to Doofenshmirtz Evil, Inc., only to be trapped by Dr. Doofenshmirtz.
As Candace prepares for the dance and Phineas and Ferb put the finishing touches on their project, Dr. Doofenshmirtz explains his evil plan: when he was young, his heart was broken by his true love. He has decided to steal all the Valentine's Day presents and launch fireworks from his Fireworks-spell-inator to announce his new holiday, Broken-Heart Day. Perry escapes and a fight ensues.
Jeremy arrives at Candace's door and gives Candace her present: a gondola ride. Perry attaches all the stolen presents to the Fireworks-spell-inator and escapes, returning to Phineas and Ferb as Valentine's Day gifts rain from the sky thanks to Agent P.
