Mona is a young woman, engaged to a man who never shows up. She relies strongly on her supportive friend, Anne. Mona suspects that Anne's psychologist, Dr. Lark, is acting funny towards her friend, and decides to investigate. Mona and Anne will find themselves embroiled in a strange world of psychiatry and fanaticism, in which both young women's lives will be endangered.

Choreographer August Bournonville's stirring movements are brilliantly showcased in this Royal Danish Ballet version of one of his finest works, inspired by a visit to vibrant Naples, Italy. The fairy-tale story follows passionate young fisherman Gennaro (Arne Villumsen), who searches for his beloved Teresina (Linda Hindberg) when she disappears during a storm. Vivid set designs and bright costumes add to the production's exuberance.
