In a similar theme to the recent Oscar nominated 'Room', this new BBC drama also tells the story of a woman who escapes captivity. Ivy Moxam was just thirteen-years-old when she was kidnapped and locked in a cellar for thirteen years. While the programme kicks off with her escape, the drama itself deals with her difficult reintegration back into society, although her sister firmly believes she's an imposter. Actress Jodie Comer takes the lead here, who you might know from Doctor Foster and My Mad Fat Diary, while it also stars Cilla's Aneurin Barnard.
