Stephen Milner is a solicitor, but he fits uneasily into the world of Lewis Strange and Partners, who are an upmarket firm of solicitors. The film follows Milner's fraught relationship with a lucrative client, Ron Jesson. When one of his offices goes up in flames, the press are convinced that Ron arranged the fire for insurance purposes. Milner also has to cope with an estranged wife, batty mother and debt ridden younger brother.
