Drugged with GHB, Ros Tyler (Eve Best) has no recollection of her weekend activities. When she awakens, however, she discovers that she has been raped, and her roommate has been murdered. Will (Andrew Lincoln) is assigned to the case as Lead Investigator. When Will and Ros slowly find attraction to one another - she for the security and he for the frailty - their desire for justice, and vindication, leads them towards a difficult and illegal action.
