Tortured Dust.

The culmination of a series of autobiographical films that Brakhage made about his family (collectively known as The Book of Family), Tortured Dust was shot as the filmmaker's children from his first marriage were beginning to leave the house, and edited during Brakhage and his first wife Jane's impending separation. The first half concentrates on Brakhage's teenage sons as they move around the cabin that has been their home for almost 20 years, and the second half turns towards the filmmaker's three daughters.
