Before 9/11, Keith played poker with his friends on a weekly basis. This was very important to him, giving a sense of stability to his life after he separated from his wife, Lianne. The friends played intense, high-stakes games, betting lots of money. Over time, they made stricter and stricter rules for themselves—limiting socializing so that they could focus on poker, for instance, and even banning food breaks—until one day the entire system of rules collapsed under the weight of one person's hunger.
The games end suddenly when three of the five six players die or are injured in the tower collapse. After Keith reunites with his family, he tries to share his love of poker with his son. Eventually, realizing he can't reintegrate into his family after all, he joins a professional poker circuit.
