 Bud Merrick and Jack Kirch rob area merchants at gunpoint, roar off on their motorcycles, then elude roadblocks by loading the two-wheelers into a closed truck driven by Grayson (their leader). They rob a residence and escape with $10,000 cash, but a telephone lineman spots them loading the motorcycles and notifies the Highway Patrol. Dan Mathews and his officers chase the suspects onto a rural network of dirt fire roads. Grayson hijacks a fire marshal s truck and sends Merrick and Kirch off on their motorcycles. Wearing the marshal s uniform, Grayson attempts to misdirect Dan and his officers. When the effort backfires, Grayson is captured and Merrick and Kirch find themselves bottled in on the narrow and treacherous fire roads.
