Rusalka plot
An apprentice monk rescues a naked girl from the ice. It turns out to be a water nymph. She suddenly disappears, but returns again and again. She wins the boy's heart with her flirty flirtation and her beautiful singing. The young monk's elder master soon realizes that the water nymph is the drowned ghost of a girl he loved in his youth and then cheated on. He tries to protect his naive student from her supernatural revenge. But if the water nymph in the old monk recognizes the man who once rejected her, it may not be the young apprentice who is in danger.
