Rod Kimble is a naïf, a slacker living in a small US town with his mom, his younger brother, and his stepfather whose respect he craves. He also misses his dead dad, whom he thinks was Evel Knievel's back-up. Rod, a man-child, believes that he is a stunt man. When his stepfather needs an operation, with help from his brother and his slacker pals, Rod hatches a plan to set a school-bus-jumping record on his moped. First, his crew and he have to raise money to rent the buses and build the ramp.
