Tracing the evolution of motion simulator rides--"thrill rides"--from 17th century wooden ice slides to the computer designed rides of the information age today. Presently, filmed motion simulation has fast become a source of adventure for curious and cautious entertainment seekers, alike. The documentary shows the technology involved behind-the-"screams" necessary to create these ride films as it takes the audience on rides that some viewers would never dare to attempt--including trips on Big Shot at the Stratosphere, Las Vegas and the roller coasters Kumba and Montu, located at Busch Gardens, Tampa Florida.
