David boards a flight to visit another doctor whom he thinks has information that might help him with his problem. But, when the pilot and stewardess drugs the rest of the crew in an attempt to bail out of the airplane with stolen property, David and a young boy named Kevin try to land the jetliner.

While hitchhiking, David gets picked up by a woman truck driver. When she shares with him her intent to get her father's tanker truck back from the highwaymen who stole it, he tries to talk her out of following through with her plan. When that doesn't work, he takes it upon himself to help her out.
