Johnathan accepts and learns the ropes of Rollerball: The players are on Rollerblades, trying to bring a heavy metal ball into a high goal. Also, there are motorcyclists around to bring momentum to the players. Oh yes, and there are no rules in the game. During his skyrocketing career, Johnathan has to experience what Alexi has found out: Blood brings more viewing pleasure to the audience.

In a final game, Johnathan and his team have to fight for mere survival against their real opponent - their boss Alexi Petrovich.
