It was just another day on the BMX street course for Billy Cruz. He lunged down the pipe, rode the ramp high into the air and tweaked his bike for a perfect Superman, when suddenly he lost his grip on the seat. Cruz hit the concrete hard, and wound up in hospital with several broken bones. Six long weeks later, Billy finally got back on his bike. But now, he couldn’t help but hold back a bit on his tricks, and his scores were starting to suffer. To add insult to injury, Billy’s best friend, Penny, had been acting strange since the accident.
