Part 2 of the concluding chapter of Stephenie Meyer’s fantasy saga begins with Bella (Kristen Stewart) re-awakening as a vampire.
She sees and hears everything, before contentedly falling back into the arms of her lover Edward Cullen (Robert Pattinson).
Soon after, however, best friend Jacob (Taylor Lautner) confesses to Bella that he has imprinted on their half-mortal, half-vampire offspring, Renesmee (Mackenzie Foy).
Once the young mother recovers from the shock and accepts Jacob as her daughter’s protector, Bella and Edward settle into domestic bliss.
Alas, their joy is short-lived when Edward’s cousin Irina (Maggie Grace) mistakenly identifies Renesmee as an immortal child – an abomination under ancient vampire law.
She reports her fears to the Volturi, the vampire counsel led by Aro (Michael Sheen), Caius (Jamie Campbell Bower) and Marcus (Christopher Heyerdahl), and they marshal an army including sibling guards Jane (Dakota Fanning) and Alec (Cameron Bright) and enforcers Demetri (Charlie Bewley) and Felix (Daniel Cudmore), leading to a battle royale between the Volturi and the Cullens.
Airborne vampires and snarling werewolves tumble acrobatically across the screen locked in mortal combat, their desperate struggles ended with a sickening snap of a neck or crude decapitation.
