"A long time ago, in the underground realm, where there are no lies or pain, there lived a Princess who dreamt of the human world. She dreamt of blue skies, soft breeze and sunshine. One day, eluding her keepers, the Princess escaped. Once outside, the brightness blinded her and erased every trace of the past from her memory. She forgot who she was, and where she came from. Her body suffered cold, sickness and pain. Eventually she died. However, her father, the King, always knew that the Princess' soul would return, perhaps in another body, in another place, at another time. And he would wait for her, until he drew his last breath, until the world stopped turning..."
"...because it is in pain that we find the meaning of life..."
By the way, this movie is by Guillermo del Torro (Spain) with english subtitles. If you have watched this movie and you enjoyed it then you must also watch "The Orphanage" by the one and only Guillermo Del Torro. Another truly beautiful film.
