A dream holiday becomes a nightmare for a young British couple who seemingly have it all, as heartbreak turns into fury and revenge.

Today is the day Ivy Moxham will escape from the cellar that’s been her prison for the last 13 years. Today is the day she’ll return to her home, to her family, to her life. Today is only the beginning.

Thirteen 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. Ivy Moxham is a young girl. Ivy Moxham is a woman. Ivy Moxham is whoever you want her to be.
