Tangled

A drop of pure, magical sunlight falls to earth and sprouts a flower with healing properties. Upon discovering it, an aging Mother Gothel hides the flower and uses it to stay young for centuries, until royal soldiers from a nearby kingdom find and uproot it to save their ailing Queen. Shortly thereafter, the Queen gives birth to a baby girl with golden hair. Gothel discovers the hair has the same powers as the flower, but turns brown and becomes powerless when cut. She abducts the infant, names her Rapunzel, and raises her in a hidden tower, using her hair to stay immortal.
