Childhood sweethearts David (Woody Harrelson) and Diana Murphy (Demi Moore) are a married couple who travel to Las Vegas, hoping they can win enough money to finance David’s fantasy real estate project. They place their money on number 8 and lose. After gambling away all of their savings, they encounter billionaire John Gage (Robert Redford). John is attracted to Diana and offers David one million dollars to spend a night with her. After a difficult night, David and Diana decide to accept the offer, and a contract is signed the next day. John flies Diana to a private yacht, and it is assumed that their arrangement is consummated.
Although he had hoped to forget the whole incident, David grows increasingly insecure about his relationship with Diana, consumed with a fear that she remains involved with Gage; this insecurity is heightened by the fact Diana discovers that Gage has bought their home/property while it was going into foreclosure. Because of this tension on their relationship, David and Diana separate. John actively persists and renews his advances on Diana. Although she initially resists, Diana eventually consents to spending time with him, and a relationship develops. David, meanwhile, realizes he cannot go on without the love of his life. When Diana files for divorce, David makes one final attempt to win her back.
John sees how Diana looks at David and recognizes that, even if she stayed with him, their relationship would never achieve the intensity she had with David. In John’s presence, David gives the money away. Then John misleads her into thinking that she was only the latest in a long line of “million dollar girls”. She leaves John and returns to David.
