In an attempt to settle an old long-lasting score with Frank Chaney, the pilot and leader of The Blue Thunder Unit, the crazed comedian who calls himself "P.V.C." contacts Chaney, Braddock and the rest of the team and warns Chaney personally that he is going to blow him out of the sky for what he did a year ago when he destroyed his aircraft with a 12-gauge shotgun during an unsuccessful drug bust while he was a police officer, plus to make sure that he succeeds in transporting a scheduled shipment of drugs over the Mexican border. Still continuing to wipe out airborne police units when very cannily evacuating the entire Astro-Division Building, and with the acknowledge of how the whole division works, using a fake explosive device as a decoy, Chaney decides it's time to settle the score, once and for all, before anymore innocent lifes are taken away
