Adapted from the best-selling novel by author Clare Allan, this gripping drama follows the unlikely friendship between a psychiatric patient who lives to sponge off the system, and the newly arrived patient who causes her to question everything she ever thought she knew.
N (Anna Maxwell Martin) has spent the last thirteen years living in a North London psychiatric ward. She’s made it her mission in life never to be released and she’s willing to do whatever it takes to remain institutionalized for life.
Her life is changed forever with the sudden appearance of a new patient named Poppy Shakespeare (Naomie Harris), an elegant yet temperamental woman who insists that she isn’t insane. But while N can’t understand Poppy’s reasons for wanting to escape the mental ward, she’s more than happy to help her new friend try. The only problem now is that in order for Poppy to qualify for release, N must help prove that she’s not insane. But how does one go about proving their sanity when in order to do so they must first appear to be mad?
