While waiting for the night rehearsal of the ballet Swan Lake, the lonely twenty-eight year-old ballerina Marie receives a diary through the mail. She travels by ferry to an island nearby Stockholm, where she recalls her first love Henrik.

Bergman’s personal and professional breakthrough, this moving look at adolescence and memories of a lost love begins the filmmaker’s interest in idyllic summertime settings, a motif revisited in Smiles of a Summer Night and Summer with Monika. A defining film in the director’s early career.
