The Twilight Saga: Eclipse, starring Kristen Stewart, Robert Pattinson, and Taylor Lautner, was released in 2010 and is the movie version of the Twilight Sage Novel Series written by Stephenie Meyer. The movie is often simply referred to as Eclipse because it is the third movie for the entire saga of Twilight films. In the third film, the movie primarily takes place in the city of Seattle, located closely to the Forks area, which is where Bella, who is played by Kristen Stewart, is currently located. During the film, several bad vampires, including Victoria and Riley Biers, are looking to attack a number of innocent bystanders as a way to create an entire army of new vampires who can help to destroy Bella because of her involvement with the Cullen's.
In the meantime, Bella is focusing on her options and discussing the possibility of becoming a vampire, which is something that she truly wants, even though the entire process is complicated. Bella is currently 18 years old during the film and is hoping to have Edward turn her into a vampire because she wants to remain immortal, much like Robert, instead of aging and becoming older because Edward is forever young and will remain 19. Edward, in the meantime, is constantly worried about the safety of Bella, especially against the werewolf pack. However, Bella insists that Jacob would never harm her or allow his werewolf pack to harm her either. Jacob eventually confesses his love and admiration for Bella but she gets mad and hits him in return, which causes tension. After a period of time, Jacob apologizes for expressing his love for her.
Aside from the usual drama between vampires and the murder of Victoria, Bella eventually decides to go about things in the fashion that Edward had hoped for. She will get married to him and make love with him so that she can become a vampire too. She tells Edward that she does not feel normal and never will be, so she feels prepared to take on this journey with him and eventually become a vampire, leading to their engagement.
