Cam O'Mara, grandson and younger brother of bull-riding champions, is not interested in partaking in the family sport. Cam is a skateboarder, and perfecting his tricks -- frontside flips, 360s -- means everything until his older brother, Ben, comes home from Iraq, paralyzed from a brain injury.

What would make a skateboarder take a different kind of ride? And what would get him on a monstrosity of a bull named Ugly? If Cam can stay on for the requisite eight seconds, will the $15,000 prize bring hope and a future for his big brother?
