Pitch is back with one thing on his mind: Revenge. And his anger will be taken out on a certain Frost who had ruined everything for him. He knows hurting Jack will hurt the others. And by hurting Jack, he takes away Jack's memories of his past. His family, sister, friends, and how he became a Guardian. Back where he started, Jack doesn't know if he can go on without knowing his past like before. Only difference is, the Guardians are there with him this time to help.
