Operation Thunderbolt is the exciting sequel to Operation Wolf. An airliner is hijacked by terrorists en-route from Paris to Boston, who threaten to kill all hostages on board if their mates aren't released from jail. Instead of reaching its destination, the airliner makes a landing in Kalubya, Africa, and all the hostages are hidden in various locations. The authorities have asked the hero from Operation Wolf to rescue the hostages, but only this time, the hero brings his friend along for the ride.
