Three of the world's largest theme parks get the behind-the-scenes treatment, built around interviews with the architects and project managers who designed them. At Siam Park in Tenerife, engineers explain how they built the Tower of Power slide and the Mai Thai River through volcanic terrain. At Europa Park in Germany, designers walk through the construction of themed zones like Adventureland and the Blue Fire roller coaster, discussing how a family-run park grew into one of Europe's biggest tourist draws. The Ferrari World segment in Abu Dhabi covers the engineering behind Formula Rossa, one of the fastest roller coasters built, and the desert-climate challenges of housing it under the world's largest space-frame roof. Throughout, park staff, ride engineers, and safety teams describe the daily operations that keep the attractions running for millions of annual visitors. The film moves park to park rather than digging into any single story, but the interviews and construction footage give a real look at what it takes to build and run facilities on this scale.
