When a young athlete in a wheelchair comes into the shop for a tattoo, the artists are intrigued by the sport he plays. So, days later when the young man calls the shop to invite the artists down to the gym to play, the games really begin. But can the artists survive their turn at Murderball? Meanwhile, Carey's in his own hot seat as he agrees to a new sport, Super-Moto. It's faster and crazier than regular motocross and he has only a few weeks to get ready for his first competition.
