Ondine is the story of Syracuse, a simple fisherman who catches a beautiful and mysterious woman in his trawler nets. The woman seems to be dead, but then she comes alive before Syracuse's eyes, and he thinks he may be seeing things. However, with the help of his irrepressible daughter, Annie, he comes to believe that the fantastical might be possible and that the woman (Ondine) might be a myth come true. Ondine and Syracuse fall passionately in love, but just as we think the fairytale might go on forever, the real world intercedes.
