Gary does his usual routine to help others, and finds himself involved with the robbery of an ancient Chinese helmet that was stolen from LA. Detective Sammo Law from the Los Angeles police department is in Chicago looking for the missing helmet. After investigating Gary's involvement with the case, Sammo and Gary find out Gary accidentally bought the helmet as a piece of an art decoration object. Unfortunately the helmet is stolen again, forcing Sammo and Gary to team up to get it back, while trying to stop the man who stole it and his niece from being murdered by international smugglers who want the helmet.

In this crossover episode, which continued from the Martial Law episode "Honor Among Strangers", Walker comes back from Los Angeles with Sammo Law (Sammo Hung) to track down the white supremacist Cliff Eagleton, whom they had caught but had later escaped custody. To help determine Eagleton's next target, Sydney and Gage go undercover to gather information, with Gage infiltrating Eagleton's hate group and Sydney going to a ranch owned by the man who is financing Eagleton's operations.
