...The story simply put is that a brother and sister try to keep the family together after the parents (specifically the mother) die.
Tied in there though are elements of ...how the addage that blood is thicker than water might well prove to be a damning rather than positive virtue.
The performances are storng from the main family members but the blot on the landscape is the sisters lover who disturbes their already disturbed little family.
He interacts badly is poorly drawn and seems much less real than the others which makes it difficult to feel any empathy for him.
This i sa film you need your brain in gear for but is well worth the effort expended on it
