In a small town in Maine, all the fairy tale characters you can imagine are caught in a limbo between two realms, ensnared by a formidable curse. There is only one person who understands the reality of their situation and has the power to lift the enchantment.

Emma Swan, a 28-year-old bail bonds collector, has been fending for herself ever since she was left as an infant. Her life takes an unexpected turn when Henry, the son she gave up for adoption years ago, tracks her down. He reveals that she hails from another world and is actually the long-lost daughter of Snow White.
