A Clear and Present Danger

Eine Miliztruppe überfällt Banken in und um Los Angeles mit Luftunerstüzung. Die Blue Thunder Besatzung wird auf die Bande angesetzt und deckt eine Verschwörung auf.

A paramilitary group who call themselves the "Posse Magistratus", have been the prime suspects for a series of bank robberies, and one particularly involving a heavily-modified World War II fighter plane. In order to track down this plane and stop the whole game, Chaney and Wonderlove attempt to track it down, based on various aerial police sightings. When accomplishing this, Chaney spots gun mounts on a plane that they performed an unauthorised thermograph upon, and results in not in the state of valid evidence to charge the Sheriff who owns it for the state-threatening operations. However that same day, the same World War II figher plane attacks them, and ends up being shot down by Chaney in Blue Thunder. To possess reliable and sufficient evidence to charge the ''Posse Magistrates'' of the crimes they have took out, Ski goes undercover as a mechanic.
