Once Upon a Time (TV series) [SEP] Introduction
Once Upon a Time is an American fantasy adventure drama television series that aired for seven seasons on ABC from October 23, 2011 to May 18, 2018. The action alternates between two main settings: a fantastical world where fairy tales happen; and a seaside town in Maine in a town invented for the show, called Storybrooke. The "real-world" part of the story unfolds with the characters of Emma Swan (Jennifer Morrison) and her 10-year-old son, Henry Mills. Henry discovers the other people of the town are fairy-tale characters; and the audience is shown the backstory of the town's people as fairy-tale characters, in conjunction with their unfolding stories in the "real-world".
