Der geheimnisvolle Spiegel.

A mirror in a creepy old Bavarian castle has the magical ability to reveal the future of whoever looks into it while the full moon shines brightly. A series of characters looks into the glass to learn their fate, and most are unhappy with what they learn. In the end, the hero smashes the glass and then commits suicide. After he is dead, the mirror magically reassembles itself into a whole as before.
