Christian Petzold (Phoenix) boldly reimagines the ancient myth of Undine in this suspenseful tale of romance and betrayal in modern day Berlin. Undine (Paula Beer) works as a historian lecturing on Berlin’s urban development. But when the man she loves leaves her, the myth catches up with her: Undine has to kill the man who betrayed her and return to the water. Will Undine defy fate when she meets a diver (Franz Rogowski) who offers her a chance at new love?
