A Dark Adapted Eye (1994)

Starring: Celia Imrie, Helena Bonham Carter and Ciaran Hinds as Paulo.
Synopsis: Set in the 1950's, it is a dark and brooding tale of a seemingly close-knit suburban family whose facade of normalcy hides a murderous sibling rivalry. At its center are two sisters--and the angelic, golden headed toddler each claims as their own natural son. A series of bizarre revelations finally exposes the shocking truth behind their sedate provincial existence. Standing as a witness to their bitter battle is their niece, Faith, who is left to tell the story of how she lost both aunts--one with her blood splattered on the nursery wall, the other hanged for her sister's brutal and senseless killing.
