Brothers and Sisters is a 1980 British crime drama film directed by Richard Woolley and starring Carolyn Pickles, Sam Dale and Robert East.
When Jennifer Collins, a part time prostitute, is found murdered, two upper-class brothers become suspects.
Neither have alibis and although political rhetoric divides David Barratt, a self indulgent 'revolutionary' living in a communal house, from his brother, James, a right wing army major, both men are linked by their shared sexual hypocrisy.
James, it seems, prefers secret liaisons with prostitutes to sleeping with his wife while David, who has been sneakily conducting an affair with Theresa, Jennifer's sister employed by James as a nanny, bleats that he has just been "trying to work out new codes of sexual behavior", when challenged by Tricia, his live-in lover.
Woolley was inspired by the Yorkshire Ripper investigation to make the film.
