This movie is an old film. It starts with a baby abandoned by his parents in a ship, and one of the cruise ship workers adopts him. Fast forward several years, the baby (who is now a boy) learns how to play piano. Fast forward again, the boy (who is now an adult) is a professional pianist, and gets invited to duel another professional pianist.
Also, the setting is located on the same cruise ship, where the man was born and raised throughout his whole life.
It was quite a sad movie when I first watched it, and I’d like to watch it again.
