Carol demands a divorce from Simpson when he is called to the hospital in the operating room to perform emergency brain surgery on Johnny.
While leaving the hospital, Simpson is chased by the grief-stricken Jessica, who swears revenge on Johnny's "killer".
At a golf club, Simpson and Carol are playing when they decide to make another attempt to patch up their marriage.
Simpson regains consciousness to find an Alsatian dog barking at him, tied up inches away from him.
Jessica then forces Simpson to eat dog food and lick her bare abdomen smeared with his own blood from a wound she inflicts on him.
A melancholic Jessica engages in further sexual games with Simpson and eventually recalls something that changes her mind about Johnny.
Months earlier, during a vacation getaway to Venice, Italy, Johnny bought Jessica a bracelet to symbolize their love for one another.
The two lovers kissed during the movie, but Jessica was horrified to discover that Johnny was simultaneously letting Nicky go down on him.
Jessica goes to her bedroom, disrobes, lies down on her bed, and puts the pistol to her head, intending to kill herself.
