Michael Fassbender narrates this documentary about the history of Formula One racing. The film chronicles the development of Formula One from the 1950s through to the present day, examining the dangers of racing, particularly in the '70s when the cars became faster but safety measures were still poor. After a number of fatalities, including that of promising young Frenchman François Cevert in 1973, improvements were made to limit the dangers to drivers. The documentary features interviews with Jackie Stewart, Mario Andretti, Niki Lauda, Lewis Hamilton and Michael Schumacher.
