Jimmy Harper (Gary Webster) loves to gamble and enjoys enough success to bring him to the attention of a group of men who play for big money. Soon Jimmy decides to change his name to James Harper, to reflect his increased importance, and seeks a way out of his job in a factory. However, as the stakes in the games increase, Jimmy/James may begin to wonder whether he is in over his head and has risked too much...
Unfortunately the movie The Big Game is not yet available on HBO Max.
