The first episode looks at the men behind the machines and this obsession. Men such as Dave and Steve who have built a bike from scratch, self-confessed metal head PJ who brings a whole new meaning to bringing your work home with you and Chris, Great Yarmouth's beach cleaner and legendary bike builder. The film ends with them arriving with their machines at this breath taking landscape ready to find out if they can become members of an elite group: the fastest men on earth.

This follows the men and their machines for a week of land speed racing on the Bonneville salt flats. It is a place where either parts or records are broken.
