The fantasy plot is set in two worlds - modern one and magic one. Life of a 28-year-old Emma Swan changes when her 10-year-old son, Henry, from whom she refused many years ago, finds Emma and declares that she is the daughter of Prince Charming and Snow White. Needless to say, the boy has no doubt that there is an alternative parallel fairy-tale world - the city Storybrook in which Emma eventually gets. Gradually, the heroine becomes attached to the unusual boy and a strange city, whose residents forgot whom they were in the past. And all because of the curse of the Evil Queen (who is also Henry's adoptive mother), by which the witch stopped time in the dreamland. However, they should lend a hand - and a fairy tale comes to life. An epic battle for the future of both worlds begins, but to win, Emma will have to accept her fate.
