A gentleman's agreement between a hit man and his victim develops in a barren suburb of Paris. When Kopas steps into the office of the financial investor Zimmerman, the latter already knows the reason why. Zimmerman is the unhappily married but adoring father of an eight-year-old daughter. He's involved in murky business with his partner, whom he knows is chatting up his wife behind his back. Zimmerman tries to make a deal with his murderer, because he needs a couple more days.
