Grand Prix of Europe

Edda is a talented young mouse who loves racing and works at her family's amusement park on the outskirts of Paris. After her mother's death, the park struggles as her father falls behind on loans from shady lenders. The looming threat of losing the park sets the stage for her big ambition: to race in the Grand Prix of Europe.

Edda sneaks into Ed's car backstage and ends up driving it through the streets of Paris. Ed catches her just as the car speeds away, and the two strike a deal: she will take his place in the Grand Prix in exchange for half the winnings to save the park. Ed disguises Edda as a superfan who has won a contest to accompany him.

In the initial Paris race, Edda follows Ed's guidance through a two-way earpiece. An unknown opponent sabotages her by greasing the wheels, causing a spinout. She recovers to finish 30th, narrowly avoiding elimination, while Ed doubts that sabotage occurred.

During the Alpine race, Edda again detects interference as snowball obstacles start pursuing racers. She avoids them and still finishes 10th. She grows convinced that Nachtkraab is behind the sabotage, though Ed refuses to accept it.

In Italy, Edda is in contention to win alongside Nachtkraab and Magnus when a windy blast knocks her off course. The accident ruins her chances of victory. After the race, she tries to inspect Nachtkraab's car and is penalised with a 1-minute starting penalty in the final race for tampering.

Having recovered from his injury, Ed fires Edda from the team. The termination comes as tensions flare over trust and performance. Edda is left to cope with the consequences while the sabotage plots unfold in the background.

Edda uncovers that Magnus is behind the sabotages with a fleet of magnetic drones. Böckli, a racer who knew Ed, explains that Ed learned to rely on others when he was an orphan. This revelation fuels her resolve to expose the truth before the finals.

Edda tries to warn Ed about Magnus's drone plan as the finals approach. Ed remains focused on the race and dismisses her concerns. The lack of trust sets up a tense, high-stakes showdown on the track.

The London final begins, and Magnus's drones travel into the sewers to interfere with the racers. Edda uses her father's vehicle to pursue and disrupt the drone activity. She manages to disable one drone, allowing Ed to begin closing the gap.

As Ed nears the finish, he finds Edda being pursued by drones. He sacrifices victory to save her, turning his car around and landing onto a passing underground train to stop it from crashing into the crowd. The rescue underscores their teamwork and the stakes of the race.

Magnus wins the race and a trophy, but Ed and Edda expose his sabotage, and police take him away. Nachtkraab finishes second and, recognizing Edda's driving talent, passes the trophy to her.

The prize money is used to pay off the park's loans, saving the family business. Edda forms a racing partnership with Ed and Böckli, setting up future collaborations on the track.
