Ernest and his girlfriend Juliet board the train and find themselves among the entire creative elite. Then suddenly, a murder occurs. In an instant, everyone becomes a suspect. And Ernest too. "Seven writers board the train. At the end of the journey, five will get off it alive. One will be in handcuffs."
