Speed is a drug. Like many other passions and desires, it can ruin lives.

A Fatal Addiction tells the story of two families' with widely different backgrounds.

Frank Cartland was born as the motoring age began. His family had been village blacksmiths' for many generations. From a humble and often harsh childhood, he manages to retain an optimistic outlook on life.

Privileged George Marshall was born into an old, wealthy family and grew to share Frank’s passion for racing machines. The horrors of the first world war have shaped the lives of both young men, it's consequences never leave them. But soon the ambitions of both men are driven by the drug of speed.

Frank began by repairing bicycles but motorcycles and motorcars quickly became his addiction. This addiction comes at a high price - both mentally and physically. 

Throughout the 1920’s and 30’s this joint obsession with fast machines put the two men on the same path despite their contrasting lives.  There is constant drama on and off the dangerous racetracks of Brooklands, the Isle of Man and Le Mans as they strive to fulfill their racing dreams.

The influence of the beautiful and powerful women in their lives bring unexpected and eventually tragic results. Stakes are high, success and racing glory are all that matter. Loosing either can only bring misery, pain or even death.

For Frank Cartland and George Marshall passion on and off the racetracks is fueled by their addiction to speed.
