an indiana jones type guy and a group of his friends were holding a symposium at a metropolitian university. afterward they boarded a private plane only to be chased into the sky by nazi-types in helicopters and cessnas. our heroes manage to escape the dangerous airspace, but are followed by a single plane. they fly toward a smaller airfield in a more rural setting. once they get away from the city lights they turn off their guide lights, making it impossible for the bad guy to see them on the moonless night. the bad guy is forced to land and give himself up to police after several hours of fruitless searching. after several tense more hours at the airfield, the plane with our heroes returns and lands safely at the airfield.
