Food poisoning strikes the pilots of a passenger plane. The stewardess seeks medical help from the only doctor on board, but the situation is critical and the pilots are out for the flight. The doctor is rather despondent over the loss of his own son, a pilot, who was killed in an air accident, and whose body is on this very flight. The doctor was a hobby pilot in the past and must take control of the plane. He is talked down by a friendly military pilot who knew his son.
