Low-budget and light on plot, SUPERCROSS: THE MOVIE focuses on its motorcycle races. Like '40s musicals, the movie arranges a loose-goosey plot to showcase fabulous dance numbers, here involving motorbikes and sand, smash cuts and frequent slow motion. Following a stunning first outing at a public race, they're both noted by Team Nami owner Clay (Robert Carradine), who hires K.C. to block other racers from endangering his son Rowdy's wins. Bald, inked, and vaguely egomaniacal, Rowdy (Channing Tatum) is the film's designated villain, though he's hardly colorful enough to warrant much attention.
The brothers eventually come to an understanding, though not with much help from adults. (No mothers in sight in this movie, but a pile-on of dads, including the dead one, a bad one, and a good one.) The races chart their changes: as the courses and crowds get larger, Trip and K.C. start making choices that are less selfish. But they never lose sight of their goal to "get famous."
