Cocky, overconfident motocross champion Jim Dancer and his more mature and levelheaded bike racing buddy Steve Mitchell decide to trek from Mexico to Canada via an unmarked off-road route. During their eventful pilgrimage the carefree fun-loving (and seeking) protagonists encounter a mixed bag of folks who include a perky middle-aged lady who wrecks cars for a living, two sexy swinging babes, a friendly farmer, and a hotshot aspiring motocross rider teen who challenges Dancer to a race. This latter episode ends in tragedy, with the kid taking a fatal spill off his bike. So the kid's gung-ho militant gun fanatic father decides to hunt Dancer and Mitchell down in his sinister souped-up truck.

In a small town in California, the quiet citizens find their lives disrupted by boisterous, lawless oil-field workers who have infested their community.

Though Aaron's crew succeeds, the newfound power goes to some of their heads, and Aaron and Ben must again reclaim the town for the citizens.
