The Twilight Saga 01 - Twilight
Seventeen-year-old Isabella "Bella" Swan moves to Forks, a small town near Washington coast, to live with her father, Charlie, after her mother remarries to a minor league baseball player. She is quickly befriended by many students at her new high school, but she is intrigued by the mysterious and aloof Cullen siblings.
Bella sits next to Edward Cullen in biology class on her first day of school; he appears to be disgusted by her, much to Bella's confusion. A few days later, Bella is nearly struck by a van in the school parking lot. Edward inexplicably moves from several feet away and stops the vehicle with his hand without any harm to himself or Bella. He later refuses to explain this act to Bella and warns her against befriending him.
After much research, Bella eventually discovers that Edward is a vampire, though he only consumes animal blood. The pair fall in love and Edward introduces Bella to his vampire family, Carlisle, Esme, Alice, Jasper, Emmett, and Rosalie. Soon after, three nomadic vampires—James, Victoria, and Laurent—arrive. James, a tracker vampire, is intrigued by Edward's protectiveness over a human and wants to hunt Bella for sport. Edward and his family risk their lives to protect her, but James tracks Bella to Phoenix where she is hiding and lures her into a trap by claiming he is holding her mother hostage. James attacks Bella and bites her wrist, but Edward, along with the other Cullen family members, arrives before he can kill her. James is destroyed, and Edward sucks James's venom from Bella's wrist, preventing her from becoming a vampire. A severely injured Bella is taken to a hospital. Upon returning to Forks, Bella and Edward attend their school prom. While there, Bella expresses her desire to become a vampire, which Edward refuses. The film ends with Victoria secretly watching the pair dancing, plotting revenge for her lover James' murder.
The Twilight Saga 02 - New Moon
On her 18th birthday, Bella Swan wakes up from a dream in which she sees herself as an old woman. She expresses her distaste with growing older than her boyfriend Edward Cullen, a vampire who stopped aging physically at 17. Despite her lack of enthusiasm, Edward's adoptive family throws Bella a birthday party. While unwrapping a gift, Bella gets a paper cut, causing Edward's brother, Jasper, to become overwhelmed by her blood's scent and attempt to kill her. Realizing the danger that he and his family pose to Bella, Edward ends their relationship, and the Cullens leave Forks, Washington.
Edward's departure leaves Bella heartbroken and depressed for months. However, when her father, Charlie, decides to send her to live with her mother in Florida, Bella agrees to spend time with her friends. After seeing a movie with Jessica, Bella sees a group of men on motorcycles. This reminds her of when Edward previously rescued her from an assault, and she sees his image warning her to stay away. Bella discovers that thrill-seeking activities evoke Edward's preserved image. She is also comforted by her deepening friendship with Jacob Black, a cheerful companion who eases her pain over losing Edward. When Jacob suddenly begins avoiding her, Bella discovers he has become a werewolf, an age-old enemy of vampires. Jacob's pack members are on constant patrol for Victoria, a vampire searching to kill Bella due to the death of her mate, leaving Jacob little time to spend with her. Alone again, Bella returns to seeking thrill-inducing activities.
Through a series of miscommunications, Edward believes Bella has killed herself after she jumped off a cliff into the ocean. Distraught over her supposed suicide, Edward travels to Italy to provoke the Volturi, a powerful vampire coven capable of killing him, by exposing himself in the sunlight. Alice, Edward's sister, and Bella rush to Italy to save Edward, and arrive just in time to stop him. However, the Volturi determine that Bella, a human who knows that vampires exist, must either be killed or transformed into a vampire herself. Alice stops them from killing her by sharing her premonition with Aro, a Volturi elder who is able to read thoughts, in which Bella has been transformed. Returning to Forks, Edward tells Bella that he always loved her and only left to protect her. She forgives him, and the Cullens vote in favor of Bella being transformed into a vampire, to Edward's dismay. However, Jacob reminds Edward of the treaty the Cullens made with the Quileute tribe: "they will not attack each other, as long as the Cullens do not bite any humans." The movie concludes with Edward telling Bella that he will change her into a vampire if she marries him first.
The Twilight Saga 03 – Eclipse
Riley Biers is attacked by Victoria, while she's out creating an army of newborns set to destroy Bella Swan. Back in Forks, Edward Cullen and Bella discuss the complications of becoming an immortal vampire. At 18 years old, one year older than the age Edward was when he became a vampire, Bella expresses her aversion to the idea of marrying so young, though Edward refuses to turn her until they're married and she's had various human experiences she would otherwise miss. While Charlie Swan is investigating the disappearance of Riley Biers, Edward suspects his disappearance was caused by the newborn vampires. Furthering his suspicions is the intrusion of Riley into Bella's room.
Although Edward fears for her safety, Bella insists that Jacob and the rest of the werewolf pack would never harm her, but Edward is still not convinced. Bella goes to La Push to see Jacob, and returns to her home unharmed. During one of her visits, Jacob confesses that he is in love with Bella, and kisses her. Furious, she punches him and sprains her hand, and Edward later threatens to break Jacob's jaw. Bella even revokes the invitations of Jacob and his pack members to her graduation party, but when Jacob apologizes for his behavior, she eventually forgives him.
Meanwhile, Alice has a vision of the newborn army, attacking Forks and led by Riley Biers. Jacob, accompanied by Quil and Embry overhear this, which leads to an alliance between the Cullens and Wolf pack. Later, the Cullens and the wolves agree a meeting place and time to train and discuss strategy. During the training Jasper explains to Bella that he was created by a vampire called Maria to control a newborn army. He hated his original existence and upon meeting Alice, joined the Cullens with her. Bella sees the true bond between a mated vampire pair and begins to understand Jasper better. Despite her reluctance to marry, Bella realizes that spending eternity with Edward is more important to her than anything else and accepts his proposal. Edward and Bella camp up in the mountains to hide Bella from the bloodthirsty newborns. During the night, Bella overhears a conversation between Edward and Jacob, in which they temporarily put aside their hatred towards each other. In the morning, Jacob overhears Edward and Bella discussing their engagement and becomes very upset. Before he can run off to get himself killed in the fight with the newborns, Bella desperately asks him to kiss her, and she realizes that she has fallen in love with him. Edward finds out about the kiss but isn't angry, as Bella says she loves him more than Jacob.
Victoria eventually finds Bella's hiding spot, and Edward kills her while Seth kills her partner Riley. The Cullens and the Quileute wolves, meanwhile, destroy her "army", though Jacob is injured saving Leah Clearwater from a newborn. Several members of the Volturi arrive to deal with the newborn army. They also see that the Cullens are guarding the newborn, Bree Tanner, who had refused to fight and surrendered to Carlisle. Jane tortures Bree to get information, then instructs Felix to kill her, despite the Cullens' efforts to spare her. When Jane notes that Caius will find it interesting that Bella is still human, Bella informs her that the date for her transformation has been set. Bella visits Jacob in his home to tell him that even though she loves him, she has chosen to be with Edward. Heartbroken by her choice, Jacob reluctantly agrees to stop trying to come between her and Edward.
Bella and Edward go to their meadow, where she tells him she has decided to do things his way: get married, make love, then be transformed into a vampire. She also explains that she never has been normal and never will be; she's felt out of place her entire life, but when she is in Edward´s world she feels stronger, though he can kill her. They then decide they need to tell Charlie about their engagement
