Guest-starring the Silencer! Dick Grayson is forced to participate in the world's greatest motorcycle  race, a three-day affair hosted on a remote island and populated by the greatest riders on the planet. Nightwing reluctantly complies, but only to save the life of an old friend. That brings him into competition with the Silencer, who's also racing to save a friend. Only one rider can win...so who's gonna leg this one out? That's if they survive the onslaught of super-criminals in the race as well.
