A Vietnam veteran who has become a drifter helps a young, single mother avenge her brother's murder and finds himself the target of a gang of dope smugglers on the Mexican border.

Sequel to Code of Vengeance in which Vietnam vet-turned-loner David Dalton goes off this time in pursuit of his crazy former commanding officer and his trigger-happy paramilitary group, the New Patriots, who are planning a war against the U.S. Government, which they feel let them down in Vietnam.
