When a hired killer crosses paths with a suicidal shirt salesman, the resulting calamity makes for one of the funniest, most original films ever. Ralf Milan has come to Montpellier to fulfill a "contract" that a powerful crime organization has placed on a man about to testify against the mob at an upcoming trial. As Ralf waits for the man in his hotel room with gun in hand, he notices something very strange in the attaching room next door: Franöis Pignon, a cuckolded, unhappy man who is trying to hang himself, but is failing, ridiculously. Ralf finds himself compelled to protect Franȯis from his hapless attempts at self-destruction to avoid attracting attention. What develops is one odd, unforgettable friendship.
