That's what the French title means.It's one of the numerous two-bit spy thrillers which were thriving in France during the cold war.Directed by Georges Lautner,with a weak cast -with the exception of Bernard lier -,a trite confused plot involving the de rigueur stolen documents,abductions,treacheries,murders,this movie 's one originality is that the action takes place in a mine for the final sequences.Bernard Blier and Georges Lautner will do a much better job in 1963 with "le septième juré".
