In the middle of a desert somewhere south of nowhere, to a forlorn house made of metal and clapboard, a secret war advisor has gone in search of space and time. Richard Elster, 73, was a scholar – an outsider – when he was called to a meeting with government war planners. They asked Elster to conceptualise their efforts – to form an intellectual framework for their troop deployments, counterinsurgency, orders for rendition. For two years he read their classified documents and attended secret meetings. He was to map the reality these men were trying to create. Bulk and swagger, he called it.

At the end of his service, Elster retreats to the desert, where he is joined by a young filmmaker intent on documenting his experience. Jim Finley wants to make a one-take film, Elster its single character – Just a man against a wall.

The two men sit on the deck, drinking and talking. Finley makes the case for his film. Weeks go by. And then Elster's daughter Jessie visits – an otherworldly woman from New York – who dramatically alters the dynamic of the story. When a devastating event follows, all the men's talk, the accumulated meaning of conversation and isolation, is thrown into question. What is left is loss, fierce and incomprehensible. Point Omega is a deeply unnerving and brilliant work from one of our greatest living writers.
