26-year-old Ivy Moxam steps out of an ordinary house, on an ordinary street, on an ordinary day. Ivy hasn't been seen for thirteen years; she was kidnapped in 2003 at the age of thirteen.

A woman escapes from a house in Bristol. At first the police are skeptical of her story but it turns out that she is Ivy Moxam, who was kidnapped 13 years ago at the age of 13. Now begins the task of reuniting with her family and friends and restarting her life. Meanwhile, the police are trying to catch her kidnapper, Mark White, but questioning Ivy makes the details of her kidnapping and imprisonment murkier and more inconsistent. It appears that Ivy wasn't always a totally involuntary prisoner. Then Mark White kidnaps another girl.—grantss
