In this episode, Phineas and Ferb plan to create the ultimate backstory for their pet platypus, Perry the Platypus, also known as Agent P.

Meanwhile, Phineas and Ferb are in their backyard, discussing what to do for the day. They decide that creating the ultimate backstory for Perry would be a great idea and immediately begin working on their new invention.

As they begin to work on their invention, Doofenshmirtz appears with his latest invention, "Unbackstory-inator," which he plans to use to erase all the backstories in the tri-state area. Perry tries to stop him, but Doofenshmirtz is ready and uses his invention on Perry, erasing his entire backstory.

Phineas and Ferb are shocked when Perry comes back to them, acting as if he has never met them before. They realize what has happened and associate Perry's behavior with amnesia. They embark on a mission to help Perry remember his past by creating a series of backstories, each more extravagant than the last, in the hopes that one would jog Perry's memory.

Throughout the episode, the brothers explore different aspects of Perry's personality which were previously unknown to them. They create various stories, including one where Perry was an undercover agent for the Australian government and another where he was a medieval knight.

As they continue to work on their invention, they encounter several obstacles. Doofenshmirtz repeatedly interrupts their work, creating chaos and Monogram assigns them a new mission, which they must carry out simultaneously. However, Phineas and Ferb never lose hope and are determined to help Perry regain his memory.
