The incredible giant iron skeletons that populate amusement parks defy the laws of physics for millions of passengers each year across the globe.
Starting with the first attractions in Russia 4 centuries ago, this documentary traces the historical and technological evolution of these “terror tracks”, which are constantly evolving in order to generate new and extreme levels of excitement.

Although very expensive, innovative attractions are obvious sources of revenue for amusement parks, and engineers are ramping up the physiological effects with the sole intention of testing the boundaries of human resistance.
These “hell trains” have to meet draconian safety standards every inch of the way. The attractions are designed using powerful computer software, the steel structures requiring meticulous craftsmanship to keep them standing for more than 30 years without maintenance or repair.
Having scared us to death, played with our inner ear and sent our adrenaline levels soaring, today’s roller coaster designers are aiming to mess with our minds even further by incorporating images and virtual reality.

With the help of interviews with engineers, historians and technicians, the film reveals the techniques being used to take us ever higher and their effects on our bodies. But are we physically capable of keeping up with the limitless advances of technology?
