It was the second time Delon had teamed up with Rene Clement:their first collaboration produced a great thriller "purple noon" .The second attempt produced a would be comedy which is not funny at all.The plot deals with fascists in charge of finding the antifascist printing houses.It's repetitive ,ponderous and boring.Barbara Lass was then Roman Polanski's wife and they came to France together at the turning of the decade.Lass's moment of glory was short-lived but Polanski would direct a segment in "les plus belles escroqueries du monde" a couple of years later.
