No, it is a bit complicated! The cast is made up of story book characters who have been cursed by the Wicked Queen from Snow White to live a bland timeless existence in a town called Storybrooke in Maine, without knowing their true identity, and never ageing.. The only person saved from the curse was Snow White and Prince Charming's new born daugher who was found by the side of the road in reality and had a tough time growing up in the care system.
The story begins 28 years later, when her 10 year old illegitimate son tracks her down. He was adopted by the Wicked Queen, and he somehow knows what has happened and wants his mother to rescue them all from the curse. She takes him home and decides to stay and help him get rid of his "delusion".
The plot skips between pre curse the fantasy story book world and the so called real world, and it is very entertaining, if rather scary in parts..
