Based on very real and terrifying events, Until I Kill You charts the ordeal that Delia Balmer suffered at the hands of John Sweeney and her traumatic journey through the police and criminal justice system as they attempt to prosecute him for his crimes. It’s a story of the sheer will to survive, despite having to face and navigate emotional and physical torment.

Here’s everything we know so far about the upcoming ITV series.

**What is the plot of Until I Kill You?**

Based on Delia Balmer’s book Living With A Serial Killer, the series is set in 1991, where Delia leads a solitary life in London working as an agency nurse. Until one day, she meets fellow free spirit John Sweeney in a local pub and it seems like the connection she’s been searching for.

As the relationship develops, Sweeney’s artistic anti-establishment persona gives way to a darker side culminating in a series of violent attacks on Delia, during which he tells her that he killed his former girlfriend and disposed of her body in an Amsterdam canal.

Sweeney is arrested, but he is granted bail due to a catastrophic failure by the court to realise how dangerous he is. He immediately pursues Delia and subjects her to a horrific near-fatal attack – she survives, but Sweeney evades capture and disappears.

Shattered by the trauma and injuries inflicted by Sweeney, Delia bravely seeks to rebuild her life, but Sweeney returns seven years later and is arrested for the murder of another girlfriend in North London. Delia’s fragile recovery is shattered all over again as she has to face Sweeney in open court, her testimony vital to the prosecution case against him.

**Who stars in Until I Kill You?**

The Bafta-winning actress Anna Maxwell Martin (Motherland, A Spy Among Friends) will play the role of Delia while actor and director Shaun Evans (Endeavour, Vigil) is John Sweeney. More casting details are yet to be announced.

**When will Until I Kill You be released?**

The ITV series is set to land on our TV screens later this year.
