Plot.
Nick Freeman (David Essex) is an aspiring motorcycle racer, whose brother has been developing an experimental motorcycle. When his brother dies before being able to test and race the new bike, Nick inherits the responsibility to prove his brother's design. In spite of a series of tough setbacks, including the loss of his girlfriend, Nick goes into the big race at the British Grand Prix with all his energy and concentration bent on winning. However, an underhanded American racer (Beau Bridges) is also among the competitors, and is determined to ruin Nick's chances. Numerous incidents happen before Nick crosses the finish line in first place. Two completely different endings were filmed depicting Nick after he has won the race, and both versions were released.
