About ONCE UPON A TIME:

Master storytellers Edward Kitsis and Adam Horowitz ("Lost," "Tron: Legacy") invite everyone to join Emma Swan as she struggles to understand whether she belongs in New York City, where she has begun a new life with Henry, or back in Storybrooke, where things have never been simple. As she works to provide a stable environment for her and Henry, she learns that there's no place like home. But the question remains: where is that for Emma?

Welcome to Storybrooke, Maine, a small town that probably won't show up on your GPS, but it's a magical place to visit. Reality and myth merged after Emma broke Regina's curse, which had deprived the fairytale characters of their memories and trapped them in our modern world. When they finally regained their identities, our heroes were dismayed to discover that they weren't transported back to Fairy Tale Land. To make matters worse, Rumplestiltskin - aka Mr. Gold - decided to escalate his power struggle with Regina by introducing magic into the town. But this is our world, and magic always has a tendency to yield unfathomable consequences.
