'Thirteen' is a new original five part mystery thriller which follows Ivy Moxham (Jodie Comer) on the day she escapes from the cellar that has been her prison for the last 13 years. It's the day she'll return to her home, to her family, to her life. It's the day that is only the beginning.

The Moxam family had given up all hope when suddenly their loved one was thrust back into their lives - now the family struggles to piece back together the version of their lives that existed before Ivy disappeared. Mother Christina (Natasha Little, The Night Manager) insists husband Angus (Stuart Graham, The Fall) leave his girlfriend and return to the family home - never to breathe a word to Ivy of their separation, his breakdown, and all that has passed. Their other daughter, Emma (Katherine Rose Morley, Last Tango in Halifax), isn't even consulted about this and feels disgusted by it. Once again the focus shifts from her, and her imminent wedding to Craig Watts (Joe Layton, Tatau), to her sister.

'Thirteen' is an emotional rollercoaster that explores how to pick up the threads of a life half-lived and how to survive as a family under the greatest pressure: how to feel again, chance love again. It is a psychological drama about who to trust when you can't even trust yourself.
