Desconeguts en un tren

Bruno, an idle and pampered young man engaged in partying, cocktails and golf, coincides on the train with Guy, a promising architect. Because the journey is long, they talk to kill time; at first, they talk about insignificant things, but little by little Bruno insists that the other give him details about his personal life, until he discovers his only weakness: his wife, who has to sign the papers of the divorce and that, depending on how, could become a serious obstacle in your upward career. Suddenly, Bruno proposes a hypothetically infallible pact: he could kill Guy's wife and, in turn, Guy would take care of eliminating his father, who intends to leave him. without money. It seems like a perfect plan, because none of them have a cell phone to kill that person. Without even thinking about it, Guy rejects this absurd plan and forgets as soon as he gets off the train... until the news appears in the newspapers that his wife has appeared dead in strange circumstances.
