Scientist Leon Jackson defected to the Soviet Union for the love of a woman but now wants to return to the states with his son Alex.

When an Aircraft mysteriously disappears in a test flight, Steve's friend Kelly Wood becomes the prime suspect, since she was the one driving the plane at the time. But for some reason, she has no memory, except remembering seeing a Japanese Zero plane from World War 2. Since no one believes her, Steve knows he must clear his friend's name, before it's too late.

Steve's mission is to rescue an Arab prince who's going to be killed by someone who wants to be King. So Steve joins a fighter jet group called the Thunderbirds that perform aerial maneuvers. But when Steve suffers dizziness when he reaches certain altitudes, Rudy says they can treat it but it'll take time. And they need to rescue the prince so Steve tries to stay at low altitudes.

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.
