The dark siege of Storybrooke is underway as all of the resurrected Dark Ones target a living soul for sacrifice so that they can return to the realm of the living. With doom imminent, Gold advises Mary Margaret, David and the rest of the heroes to spend their last fleeting moments enjoying the company of their loved ones; Emma, however, refuses to give up, knowing that it's her responsibility to right all the poor choices she made as the Dark Swan. There's only one problem: Dark Hook. When they face off, with the fate of the town at stake, Hook's actions will devastate Emma in a way no one sees coming. Meanwhile, in the fairytale land that was, the Evil Queen tests Hook's mettle by forcing him to confront a demon from his past before contracting him to dispatch one from hers.
