Years have passed since the first film, with the shattering of the magic mirror portal spreading shards of the mirror across the world. To combat threats from the fairytale realm, an organization called Looking Glass was founded; lead by Alice, who's sanity is maintained by medicine Hatter makes for her, the princesses and Red work to locate the fragments to rebuild the portal to go home. However, the power-crazed ruler of Atlantis, Madga the Mad is threatening the world in her hunt for Prince Charming (who survived Rumple's attempt on his life) to force him to marry her so she can get his ring, which will literally allow her to rule all the land. A different Rumplestiltskin allies with Magda in exchange for Atlantis. Snow is revived to combat the threat.
