Rising tension and packs of wolves liven the trailer of The Twilight Saga: Breaking Dawn Part 1,' which is now out.

The 15-second trailer aims to charge up fans for the last Twilight movie, which opens Nov. 18.

Bella learns that Edward believes she is dead and is planning to kill himself. Trying to save him, she ends up in the vampire's nest and is now compelled to become like them. Becoming a vampire would mean immortality and eternal bliss with her loved one, and that is what Bella wants.

Jacob, a werewolf, hates vampires and is left with no option but to give up Bella, whom he is madly in love with.

The latest trailer completes the image of Edward and Bella's wedding ceremony, and Bella's pregnancy is far from being perfect.
