Cuando Bertha muere, su nieta Iris hereda su casa y se encuentra nuevamente en la casa donde ella y su prima solían jugar a disfrazarse en las vacaciones de verano. Mientras pasea de una habitación a otra, recorre los recuerdos y las cosas que había olvidado: ¿qué hizo realmente su abuelo antes de ir a la guerra? ¿De qué hombres estaban enamoradas las hijas de Bertha?
Kain, a young rock musician, is on his way from an "insider tip" to an acknowledged newcomer. Even though he often has to work at night, he leads a more or less settled life until he meets Nina. Nina, who is blind from birth, works as a switchboard operator at the post office. Her life as well is settled, and more so than for Kain the order in her life is a system of security for her.
They fall in love and as time passes Nina gets much more involved in Kain's life as a musician than she wanted to.
