Sechs Stunden Angst plot
The plane with 31 passengers is above the Atlantic Ocean and has passed the 'point of no return'. Then the director of the airport in Paris hears, via an anonymous phone call, that there is a time bomb on board. While Commissioner Bignon (Paul Dahlke) systematically goes through the passenger list and tries to sketch a perpetrator profile, panic breaks out on board and a heart patient needs medical attention. Radio contact is defective and the bomb must be found in time to defuse it with the help of an expert via radio. When the case seems hopeless, another phone call comes in.
