After Bella (Kristen Stewart) recovers from the vampire attack that almost claimed her life, she looks to celebrate her birthday with Edward (Robert Pattinson) and his family. However, a minor accident during the festivities results in Bella's blood being shed, a sight that proves too intense for the Cullens, who decide to leave the town of Forks, Washington for Bella and Edward's sake.

At first Bella exempts herself from all social activities, until she realizes she can coexist with childhood friend, Jacob Black (Taylor Lautner ). As usual for Bella, things aren't what they seem. Something is happening to Jacob that he can't explain to Bella, and their friendship starts to deteriorate. But when someone from Bella's past comes back to haunt her, everything will change again.
