Alice’s life continues to fall apart as more secrets are revealed.

The focus in this penultimate episode of Jack Thorne’s gripping drama is squarely – and uncomfortably – on Alice, Kiri’s foster mother.

Lia Williams puts in a truly heartrending performance as Alice, who we learn a lot more about this week. With shocking new evidence throwing Nate’s guilt into question, Alice is becoming increasingly unhinged as tension builds between her, husband Jim (Steven Mackintosh) and their son, Si (Liar’s Finn Bennett).

Meanwhile, a furious Miriam accuses a former colleague of leaking the truth about Miriam’s drinking, Tobi reacts badly when a lawyer offers his help, and the police stage a reenactment of the day Kiri went missing. Powerful, moving drama.
