Synopsis
The island of Jersey, 1945. The Second World War is overbut Grace's husband has not returned from the front.
Alone in a remote Victorian mansion, she brings up her children within
the menacing constraints of her strict religious principles.
Her Young daughter and son also suffer from a strange illness:
they cannot be exposed to direct daylight.
When three new servants join the family, they must learn a vital rule:
the house must always be kept in semidarkness;
no door is to be opened before die previous one is closed.
The rigorous order imposed by Grace will be defied.
Grace, the children, and those around them will take a decisive, fateful step.
