When String and Dom agree to shoot some incidental film footage for a friendly rival, they accidentally stumble across a reputed mobster hiding out in the desert with plans for a secret rendezvous with his compatriots. The mobster sends his goons out to recover the film, but when their friend ends up being killed over the footage they shot, String and Dom work even harder to try to find out what's behind their friend's murder, even though a local detective isn't convinced about their findings.

A former Vietnamese warlord, Tranh Van Zung (James Shigeta), terrorizes a small community of Southeast Asian immigrants by requiring them to pay a tithe like they would in their own country. A group of dissidents, however, stand up to the greed and refuse to pay. Subsequently, they are targeted for extermination by Tranh, who is an accomplished pilot. His men murder several of the members of the dissident faction -- that is, until String and Airwolf make a stand against Tranh's corruption and give the other immigrants a taste of what freedom is all about.
