After being captured and sentenced to die, Jo's only hope for survival lies with a Soviet defector.

St. John is following Jo in a bi-plane as she tries out a new navigation device in a helicopter over an area of wilderness, when her helicopter is suddenly struck from the ground by a laser-beam that sends her chopper crashing down. St. John's plane is also hit, but he manages to land in the nearby town of Santa Mira before he looses consciousness. Waking up the next day in the local hospital, he is infuriated that nobody seems to believe his story and is out looking for Jo. But when he arrives at the crash-site, there is no sign of the crash ever happened, and as St. John tries to find out what is going on, he finds that the small boom town is held in some kind of grip of fear...

A former female employee of the Company, who has suffered mental trauma after a Company mission went wrong, insists that she is seeing strange lights and hearing unexplained noises in the middle of the night, over her remote home and the nearby Indian burial ground in the rural town of Devil's Ridge. Jason sends St. John and Mike to investigate, and they are just as sceptical as everyone else, putting it down to her mental troubles, but the source of the disturbances is actually a stolen super-helicopter – a third version of Airwolf called ""The Scorpion"" – is hidden in the area, waiting to be picked up by KGB agents...

St. John and crew are under a deadline to recover a piece of stolen satellite hardware which is needed for an upcoming space shuttle flight.
