Twilight - Breaking Dawn Part 2

After the birth of Renesmee Cullen, Bella, now a vampire, finds herself enjoying her new life and abilities. However, the vampire Irina misidentifies Renesmee as an "immortal child", a child who has been turned into a vampire, and because immortal children are uncontrollable, creating them has been outlawed by the Volturi. After Irina presents her allegation to the Volturi, they plan to destroy Renesmee and the Cullens. In an attempt to survive, the Cullens gather other vampire clans from around the world to stand as witnesses and prove to the Volturi that Renesmee is not an immortal child.
