Pierre has four months left to live if he does not find a new liver. His only hope is a transplant from his brother, Paul. But Pierre hates Paul and has refused to see him for the past ten years. They are different in every aspect : their way of life, their tastes. Nevertheless, Marie, Pierre's fiancee, is determined to reconcile the two men. A love-hate relationship develops, disrupting the trio, recomposing the couples and even going so far as to change their personalities. After a few too many drinks and a bit of fooling around, the settling of scores between the two brothers will come to a surprising end.
