This tale of murderous revenge focuses on Ruth Ellis, the last woman to be executed by the state in England. Ellis (Miranda Richardson), a former prostitute and single mom, falls for David Blakely (Rupert Everett) when she meets him in a club. Although Blakely comes from an aristocratic background, compared with Ellis's hardscrabble upbringing, the two start a torrid affair. But when David starts to pull away, Ruth is overwhelmed by jealousy and turns to extreme measure to get him back.
