This Rebel spy was a passenger on board a Star Tours travel agency StarSpeeder 1000 one year before the Battle of Yavin. Prior to the ship's departure from a space station, Imperial agents discovered the spy's presence and attempted to arrest the Rebel. The vessel took off and fought its way past Imperial ships surrounding the space station. After being chased through hyperspace, the StarSpeeder landed and delivered the spy to safety.

During the Star Tours: The Adventures Continue theme-park ride, the Rebel spy is almost always one of the ride's passengers, chosen at random and shown on a video screen in the cabin. The passenger can be either male or female, which changes the dialogue of the Alliance representative who speaks to the passengers (Ackbar, Princess Leia or Yoda). Occasionally, the spy will not be someone in the cabin, and an image of a generic person or an alien appears instead. The spy's final destination is also randomly chosen, with the StarSpeeder reaching the Rebel fleet, a Naboo starship hangar, or a Coruscant landing platform. Merchandise sold at the parks included T-shirts and pins showing the Prowler droid from the ride and the phrase "I Am The Rebel Spy."
Exactly how the spy ended up discovered depended on the specific opening used for the ride. The spy will either have his ride be stopped by Darth Vader himself alongside a Stormtrooper contingent and a TIE fighter squadron (with Vader also trying to reel in the escaping vessel with the Force, only to find himself forced to release the escaping vessel trying to deflect blaster shots from the ship's cannons) or otherwise be discovered by a Prowler droid scanning the vessel.
Later variations of the ride were added featuring elements from the Sequel trilogy of films, starting with in 2015. Though initially the update retained the "Rebel spy" theme (conflicting with the Sequel trilogy timeline), additional updates added in 2017 for featured Kylo Ren a scene similar to Darth Vader's. In those scenes, the spy is working for the Resistance instead of the Rebel Alliance.
