Ruby's fear about turning into a wolf during the first curse-free Storybrooke full moon is confirmed when one of the town's residents is viciously murdered, and Ruby is the prime suspect; Decker - aka King George - threatens to expose David as a shepherd, not a prince, and not fit to run the town as sheriff; and Leroy stumbles upon some treasure in the Storybrooke mine that could help bring Mary Margaret and Emma back into our world. Meanwhile, in the fairytale land that was, Red Riding Hood finds a kindred spirit in Anita, a charismatic and mysterious leader of a pack of humans who, like Red, turn out to be wolves.

Cora and Hook face off with Mary Margaret and Emma in a race to secure the compass, which will point its holder to the portal into Storybrooke. But back on the other side, Regina and Mr. Gold, desperate to keep Cora out, put a plan into action that would kill anyone entering the portal - placing Mary Margaret's and Emma's lives in danger as well. Meanwhile, back in the fairytale land that was, Captain Hook travels to Wonderland and meets up with a vengeful Queen of Hearts.
