With Nimbasa City drawing closer, Ash and Co. check out an ad for the Wonder Launcher and right in front of their eyes was the girl from the ad. However, they find that the girl that was in front of them was actually Zorua, the mischievous, shape-shifting Tricky Fox Pokémon. They also meet its trainer, a young boy named Luke and his Golett. Luke explained that while working on a movie, Zorua got all moody and ran off. Later Ash and co. decide to help Luke by becoming actors in the film so that Zorua will only have one role. Will the movie be a big hit? Yes. And will Ash and co. get a new travelling companion?
The gang arrives to a building where they see a screen featuring a movie. Not much after are they surprised to see the main actress approaching them. Suddenly the actress transforms into Iris, but finally it is shown that Zorua is shape changing. A boy runs towards them, demanding his Zorua. Zorua changes into Pikachu and runs into Ash's Pikachu and jumbes up so as to confuse them. The boy lifts his Pokémon, but he is electrocuted when he realizes that the Pikachu is not Zorua. The boy goes after Iris' Axew, but sees that Zorua escapes them.
The boy introduces himself as Luke - he is making the movies, like the one they saw on the screen. His companions are Zorua (as they saw before) and a Golett. He tells Zorua is the actor - she can change into many characters and Pokémon, but sadly when Luke wanted a Captain, Zorua transformed into a princess and ran away. Team Rocket spy on the situation. They go inside and see the princess. The princess changes into Zorua, so Cilan believes that Zorua wants to be only the princess. Zorua agrees, but Luke wonders how is he going to make a movie with one character. To help him, Ash offers to help him by being the actor, with others agreeing. Luke gives Ash the role of protagonist - "Sir Ash the Pokémon Knight", Iris is the "Dragon Master Iris" and Cilan is the antagonist - the "Evil Captain Cilan". So, Luke goes off to write the scenario, Ash, Iris and Cilan making the movie equipment and Luke's Leavanny and Ash's Swadloon making the costumes.
After some time, the movie can be started. In scene one, "Sir" Ash the "Knight" and Pikachu are seeing "Captain" Cilan taking the princess. Ash is nervous, so Luke and Cilan give him advice that he needs to be himself to overcome nervousness. So, they begin anew - "The Pokémon Knight" demands from the "Captain" the princess. When he refuses, Pikachu uses Electro-Ball while Cilan's Pansage attacks with Solar Beam. With the explosion, the Captain and Princess are disappeared. This ends the scene and Luke is happy everything went right.
The scene two features the "Sir" Ash and "Dragon Master" Iris. The Knight asks him where the Princess is, but the Dragon Master will tell him if he defeats her. To do that, Pikachu uses Electro-Ball, so Axew dodges, but he isn't fast so is stricken by the attack. Luke does not know if Axew is the best character for the scene, but Cilan proposes that Axew should use Dragon Rage instead. So, they repeat, but Axew uses Dragon Rage, stopping Electro-Ball. The Dragon Master says to the Knight he should look into his heart to attack. So, Pikachu uses Thunderbolt as well to defeat Axew, but both Axew and the Dragon Master disappear.
Before the third scene, Luke tells them that he will keep the camera rolling. Ash asks him what'll they do if they mess up Cilan suggests some 'ad-libbing': improvisation on the spot. In 3rd scene, the Knight needs to rescue the Princess from the Captain. Pikachu uses Electro-Ball, but his attack is stopped by Pansage's Solar Beam. Unexpectedly, Team Rocket's Yamask and Woobat attack them, appearing in a plane and stealing the Princess (who transforms into Zorua). Cilan tells Luke to still point the camera and says they're gonna do some ad-libbing. The Captain says Team Rocket possessed him, making him do evil stuff, so he reveals to be a magician (a film connoisseur too, unsurprisingly). Golett uses Shadow Ball to destroy the plane and Pansage uses Bullet Seed to open the cage. However, Yamask uses Shadow Ball and Woobat Air Slash. Zorua is going up an falls, but Ash sends Tranquill and catches Zorua. Yamask uses Shadow Ball, but is negated by Pikachu's Electro-Ball, so Zorua falls down. Zorua goes to the gang, but Meowth appears, so Zorua transforms into a female Meowth, charming him. When Jessie and James try to snap Meowth out of this, Zorua uses Night Daze to defeat them, but Team Rocket fly away in jetpacks.
Cilan (aka the "Magician") tells Iris to transform into a princess - Iris has been the princess all the time, to fool Team Rocket from capturing her. It is almost the end of the movie, and the scene shifts to the theatre, in the part where the Knight and the Magician swear oath to protect the Princess. The movie is well appreciated by the audience and Mr Matthews himself is pleased, although he says that the battle scenes could hae been more exciting. He advises Luke to go to the Battle club at Nimbasa City. The gang hears that statement, so they will go with Luke to there as well. The episode ends with the trio and their new friend Luke saying goodbye to Mr. Matthews as they set off for the Battle Tournament.
