A wicked witch locked Rapunzel in a tall tower without doors. Whenever she wanted to enter, the witch would call, "Rapunzel, Rapunzel, let down your hair", and Rapunzel would lower her extremely long hair for the witch to climb. Years pass until one day a prince, riding through the forest, heard her beautiful singing and was captivated.

In the loneliness of the Lower Havel lowlands, one of the last bird paradise in Germany, twelve-year-old Lea lives alone with her father Lutz, a passionate environmentalist. She is on the cusp of adulthood, confronted with the challenges of the present and the pains of the past. She often feels lonely in the childhood-remote world in which she lives, in which schools are closed and people leave. Even the father, who has withdrawn from the world, is increasingly becoming a problem for Lea, who longs for fellowship.
