Der Student von Prag (1935)

Balduin is a popular, handsome student, the best fencer in town, in rivalry with his friend Dahl for the affections of Lydia, the innkeeper's niece. While the students are celebrating Lydia's birthday, the opera singer Julia Stella arrives at the inn and Balduin' is immediately infatuated with the glamorous singer. The mysterious Dr. Carpis intervenes, but the price will be higher than Balduin can ever imagine. He risks his sanity and his life - perhaps his soul - haunted by his own reflection. (imdb)
