This is Breaking Dawn Part 1 only. The rest will be in Part 2:
The invitations are sent out. Jacob turns and runs to Canada after he gets his invitation. Bella is nervous about the wedding and has a bad dream that she and Edward kill all of their guests.
Bella’s mom comes out for the wedding and Bella gets to see her one last time. Alice arranges the whole event and they have the wedding at the Cullen house. Bella is clearly nervous and doesn’t appear to want to go through with the wedding, but after she locks eyes with Edward, she becomes more confident and assured. Jacob shows up at the reception to wish Bella well and see her one last time before she is a vampire. Bella explains that they are waiting until after the honeymoon to turn her. Jacob gets upset, knowing that sex human to vampire could kill Bella. Edward rushes over to tell Jacob to mind his own business and the wolves appear as well to pull him away from the reception.
Edward whisks Bella off and they have a romantic honeymoon at a secret location off the coast of Brazil. They make love the first night but Edweard refuses to touch Bella again after leaving her full of bruises the first time. The native Brazilian maid freaks out when she sees human Bella in Edward’s arms. They spend most of their honeymoon playing chess while Bella tries to convince Edward to make love to her again.
Two weeks after losing her virginity to Edward, Bella gets morning sickness and throws up. She then realizes after seeing her box of unopened tampons, that her period is late. Bella runs to the mirror and sees a bump as if she is already a few months pregnant. Then she feels a twitch inside her womb. Alice calls Edward concerned about Bella because she can no longer see Bella’s future. The Brazilian maid tells Edward the baby will kill Bella. Edward packs their bags and takes Bella home, intending on having Carlisle abort the baby. Meanwhile, Bella has called Rosalie and enlisted her help to prevent the abortion.
Bella tells Charlie that she has gotten ill and is extending her honeymoon until she feels better. Jacob, Sam and the rest of the wolf pack find out Bella is pregnant with Edward’s baby. Sam says they have to protect their people and prevent this monster from being born. Using his alpha-wolf voice that the pack must obey, Sam declares that the wolf pack must kill Bella and the rest of the Cullens. Still in love with Bella, Jacob uses his birth right as the true alpha to resist Sam’s order. In doing this, Jacob creates a second wolf pack. Leah and Seth leave Sam’s pack and follow Jacob. Jacob tells them to go back, but they don’t listen and Jacob refuses to use his alpha voice. Jacob’s pack warns the Cullens and takes up guard duty outside the Cullen house.
Bella gets weaker and weaker as her baby grows alarmingly fast inside her. Desperate, Edward tries to get Jacob to convince Bella to abort the baby. Edward gives Jacob permission to kill him if Bella dies. Bella insists on keeping this baby. Worried, Jacob suggests that the baby might want blood. The Cullens fix Bella some O- human blood to drink that Dr. Carlisle got from a blood bank. It works and Bella gets a little stronger. Her belly is fully pregnant but the rest of her body is frail and thin. The babies weight starts to break her rib cage. Edward is still convinced that they should abort the fetus.
Suddenly, Edward hears the baby’s thoughts. He knows that the baby is innocent and not a blood thirsty monster as he had feared. Everyone but Jacob now wants to keep the baby. Bending over to clean up the blood she spilled, Bella hears a loud crack as her back breaks. As she falls to the ground her knee breaks as well. Edwards rushes to catch her head. Carlisle is out hunting with Esme and Emmett as none of them have fed for weeks trying to protect Bella from the wolves. Edward performs an emergency C section to save the baby and then uses a metal syringe to inject his vampire venom directly into his wife’s heart, hoping to save her from death.
Meanwhile, Jacob is sure Bella will die. Bella sees her new baby girl, named Renesme, and then her heart stops. Edwards tries to pump the venom through her heart and bites her multiple times trying to save her. Jacob tells him he will not kill Edwards so he will have to live with the guilt. Furious at the baby for killing Bella, Jacob goes to kill the baby. However, as soon as he sees Baby Renesme, Jacob imprints on her. Jacob sees her life and how she grows up to be a beautiful woman. He knows he will do anything and be anyone for her.
The wulf pack decends and the Cullens are out numbered. Luckily Carlisle, Esme and Emmett come back just in time. Seth and Leah fight their own brothers to protect the baby. Then Jacob comes out. Seeing that he has imprinted on the baby, the wolves can no longer harm her. Edwards explains that it is their oldest and most sacred rule.
Edward cleans and dresses Bella. Hoping that the venom will soon kick in and she will come back to life. Slowly her body begins to fill with regular body fat again, her bones repair themselves, her bite marks disappear and the movie ends with her eyes opening, showing a blood red color instead of her usual brown eyes.
After the credits, we return to Italy where The Volturi; Marcus, Caius and Aro find out about Bella becoming the newest vampire to their coven. Marcus and Caius assume their fued with the Cullens is over, but Aro assures them that it’s just getting started because they have something that he wants.
