A renowned cardiovascular surgeon, Dr Steven Murphy (Farrell) lives with ophthalmologist Anna (Kidman) and their two perfect children. Steven’s odd friendship with fatherless teen Martin (Keoghan) begins to take a dark turn as Martin manoeuvres himself into the family’s life. When he confronts Steven with a long-forgotten transgression, the full scope of his intention becomes menacingly clear.

A sensational thriller brimming with unsettling humour, this is part Greek tragedy, part Hitchcockian psychodrama.
