Convicts Terrorize Family in Their Home

by Tim
(Germany)

I remember a very hard and terrifying movie about a family terrorized by convicts. I couldn't watch it all because it was on too late.

The convicts rape the mother in the shower and kill the eldest son in the parents' bedroom. The daughter watches all of it without getting noticed and tries to save her own life and the life of her younger sister. I believe the acress is well-known.

Can anyone help me?
