The film tells the story of a couple in which the woman becomes delusional and loses her mind.

It was the third time Bergman directed a film written by Isaksson, after Brink of Life and The Virgin Spring.

[3] Sune, a theology student who has dropped out and is also the son of a priest, meets Viveka in a church.

As the years pass, Viveka grows more and more emotionally unstable due to jealousy and religious anxiety.

Sune accepts Viveka's mental problems and, instead of seeking help for his wife, obeys her increasingly bizarre commands.
