Directed by Robert Lamoureux

Film Synopsis

Germain, a second hand car dealer, has a real talent when it comes to conning his customers into buying the most unroadworthy of vehicles.  He has another talent, which is the ability to keep up several amorous liaisons at the same time.  Thanks to his chronic susceptibility for brunettes he now has to meet the romantic demands of four women - Sonia, Anne-Marie, Christine and Sophie.  Of course, the hard part is ensuring that none of these four ever finds out about the existence of the other three.  Germain manages to accomplish this feat for a while, but eventually his luck is bound to run out.  Things begin to go wrong when Germain is visited by a well-built man who threatens him with severe bodily harm unless he leaves his wife alone.  Not knowing the man's name, Germain has no idea which of his four mistresses he must give up, so he opts to do the sensible thing, which is to rid himself of the lot.  Convinced that the jealous man is the husband of the passionate Christine, Germain decides she will be the first to go.  Unfortunately, Christine is not the kind of woman who is easily offloaded.  Germain's troubles have only just begun...
