Two locals join Steve when he attempts to rescue a group of students in a stalled cable car halfway up a mountain. They must rescue the students before a tornado gets to them, but one of the men is a criminal and the plan is put in jeopardy.

Steve investigates his girlfriend's disappearance while she was piloting a new plane with anti-radar technology. He discovers one of the plane's technicians has been talking to a known trader of military secrets and starts the search for further clues.

Steve is assigned to gain the confidence of a scientist who has developed a weapon to capture soldiers non-violently, but refuses to hand over the plans to anyone for fear it could cause drastic results if used on a pilot in flight. As Steve begins to become his friend and acquire the weapon, the Russians inform the scientist they are holding his wife hostage and demand the device in trade for her safe return.

A new, deadlier Venus probe is tested in a desolate area as a demonstration for Steve and Oscar, but a threat to Oscar to either hand over nuclear weaponry or see the probe set loose on the public forces Steve to find a way to stop the probe, even though it outmatches him in many ways.

Steve's brush with death is followed by visions that may be the work of a spirit.
