Carey Mulligan is a revelation in the lead role. She is Cassie, a young woman who spends her night pretending to be drunk so that she can ensnare potential male abusers. What has lead this "promising young woman" who could have been a doctor, down this dark path? While no Oscar was forthcoming for Carey Mulligan, British writer / director Emerald Fennell was a winner. This is an astonishing film, one that will stay with you long after you have seen it.
