Marianne of My Youth(1955)

Original title: Marianne de ma jeunesse

A new teenage student arrives at a prestige boarding school in Bavaria, having not only the ability to play the guitar and sing, but also to charm animals and detect ghosts. Quickly becoming part of a secretive club of five other students, he is inadvertently stranded by them at an abandoned chateau on an island in the middle of a large lake, where he encounters an enchanting young woman who wants to escape. Also filmed in a separate French language version with largely different cast, MARIANNE DE MA JEUNESSE.
