Birmingham, 1933. Private enquiry agent William Garrett, a man damaged by a dark childhood spent on Birmingham’s canals, specialises in facilitating divorces for the city’s male elite. With the help of his best friend -charming, out-of-work actor Ronnie Edgerton – William sets up honey traps. But photographing unsuspecting women in flagrante plagues his conscience and William heaves up his guts with remorse after every job. However, William’s life changes when he accidentally meets the beautiful Clara Morton and falls in love. Little does he know she is the wife of a client – a leading fascist with a dangerous obsession. And what should have been another straightforward job turns into something far more deadly.
