The game was set in and around Anaheim, California and the Disneyland theme park and ran for six weeks from July 3, 2013, to August 11, 2013, with a finale event at the 2013 D23 Expo fan convention.
The story was about a fictional alternate history of Walt Disney and his involvement in a secret society connected to the 1964 World's Fair and an optimistic vision of the future.
Players learned about a mysterious group called "Plus Ultra", which was founded in 1889[3] and included Gustave Eiffel, Jules Verne, Thomas Edison, Nikola Tesla, and Walt Disney.
Other clues led to real-world locations, like a scanned napkin that directed players to the real-life Tam O'Shanter Inn, one of Walt Disney's favorite restaurants.
Tomorrowland co-writers Brad Bird and Damon Lindelof did a presentation in which they shared a fake picture of Walt Disney and a "newly found" animation that described the secret society "Plus Ultra".
