A short prologue teaches us,should one have forgotten it ,that WW2 put the world to fire and sword. This useless blah-blah-blah ,just to deal again with the hackneyed subject of the Nazi treasure which would be hidden somewhere (here at the bottom of the Mediterranean) ; and in the treasure-trove , there are not only invaluable diamonds but also documents which can compromise men in high places ;this gives the story a cloak and dagger side,but ,sadly,it is not fully exploited .
For the rest ,that is to say the essential ,it's a gangsters vying for the diamonds yarn ,saved by a good cast :Pierre Mondy ,overtaken by the events , Françoise Arnoul who displays her physique, veteran Marcel Dalio in a wheelchair and his attractive nurse .
The main interest of a run-of-the-mill story is Petula Clark 's presence : she performs two songs ,backed by Tony Hatch's band ; British Clark would hit the big time in America the next year ,scoring two number ones ,"downtown" and "my love" ,written by Hatch ; her part in the movie is insignificant ,but her questioning in the police station is my favorite moment.
