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.
