The story in one page
Undine is a water spirit living as a changeling with an elderly fisherman and his wife. She lacks a soul, a trait shared by all elemental beings of the fire, earth, and air, until she marries the knight Huldbrand. Marriage grants her human consciousness and empathy, but it also exposes her to the jealousy of Bertalda, a noblewoman who was the fisherman's lost daughter. As Huldbrand grows fearful of Undine’s supernatural origins and her meddling uncle Kuhleborn, he insults Undine near the Danube, triggering a law that pulls her back to the depths. When Huldbrand attempts to marry Bertalda, Undine must return to deliver a fatal kiss.
