Directed by Julien Rambaldi

Film Synopsis

Surely there is nothing better than spending a tranquil weekend in the country with your best friends?  It is always pleasant to meet up with people you like and trust, people who like and trust you in return.  But what if the people you think of as your friends turn out to be people who secretly hold you in contempt?  What if your supposed friends actually despise you and are laughing at you behind your back?  This is the situation one couple finds themselves in when they unwittingly overhear a telephone message in which the supposed friends they are about to spend the weekend with reveal what they really think of them.  Once the scales have fallen from your eyes there is no putting them back.  Disgusted by this revelation, the couple make up their mind to exact a suitable revenge on the ones who have led them to believe they are the most trustworthy of buddies.  The best friends in the world are about to become the worst of enemies...
