Plot
In Los Angeles, a friendship develops between Bill Denny and Charlie Waters over their mutual love of gambling after they are beaten up and robbed by a card player whose money they have won. Charlie, a wisecracking joker who lives with two prostitutes, is an experienced gambler who is constantly looking for the next score. He bets on poker, horse racing, boxing, and anything else that offers odds. Initially, Bill is not as committed a gambler (during the day he does a little work at a magazine while avoiding his boss), but he is well on his way to a full-blown gaming addiction.
As the two men hang out at Charlie's house, Bill's office, seedy bars, card rooms, and various sports venues, Bill becomes hooked on the gambling lifestyle. He goes into debt to Sparkie, his bookie, and hocks possessions, including his car, to fund a bus trip to Reno. At the track, Charlie spots the man who mugged him and Bill at the beginning of the film, beats him up, and robs him.
On their way to Reno, Bill and Charlie pool their money to stake Bill in a poker game. (One of the players is former world champion Amarillo Slim, portraying himself.) Bill wins $18,000 and becomes convinced he is on a hot streak. He plays blackjack, then roulette, and finally craps, winning more and more money. When Bill loses after a long streak at the craps table, he is drained and apathetic. Charlie is eager to continue gambling at other casinos, but after they split their winnings ($82,000), Bill tells Charlie he is quitting and going home. Charlie does not understand this but sees that his friend is sincere, so they go their separate ways.
