Synopsis: When Max, Berto and Jefferson track a pair of thieves stealing computer components to the annual Del Oro Extreme, Max must go undercover as Josh McGrath. As a competitor in the DOX, Josh teams up with real-life skate-boarding star Tony Hawk to defeat a slick sports agent called Grimsley and his two dirty-fighting stars, Durham and Preston. But it turns out that Durham and Preston are the robbers; and they're using nitro-chips, a high tech kind of steroid, to make themselves as powerful as Max Steel! Will Max be able to stop these supercharged bad guys before their boss Grimsley can put his nitro-chips into mass production?
