In Season 4, Belle takes on a new relationship with best friend Ben and the new role of managing Stephanie's escort business. The stakes have never been higher for Belle - accepting Ben's offer of a lasting relationship means that Belle has a real chance of happiness; but Ben is her one true friend and if she messes up, she'll lose him forever. But as Belle exceeds in her professional life, her personal life starts to fall apart … A series of misunderstandings with loyal, loving Ben, the unravelling and corruption of 'good girl' Poppy, and the introduction of dangerous and alluring vice cop Harry, all force Belle to question who she really is and what she wants her future to be. Will she give up 'Belle' for Ben and commit to being just 'Hannah' or will she cut all ties and throw herself into the world of prostitution forever?
