Racketeer Harry Starks sees Teddy Thursby, an impecunious peer of the realm with a predilection for young men, as a means of joining the Establishment, legitimising his business dealings, and obtaining real status and power.

Ruby Ryder is just the sort of faded celebrity that Harry likes, so when he turns the club into an erotic revue, he employs her to choreograph the strip shows and liaise with the corrupt Inspector Mooney over the porn racket.

When one of his former rent boys is found murdered, Inspector Mooney infers that Harry is responsible. With the help of low-life speed dealer Jimmy, Harry determines to find the truth but could it really be Harry that is to blame for the boy's death?

In the final part of the dramatisation of Jake Arnott's acclaimed novel, Harry Starks is now in prison serving 25 years.
