Until I Kill You follows Delia, one of Sweeney’s ex-girlfriends who is seeking justice over the attacks she was subjected to by her former lover.
The synopsis for the drama reads: ‘In 1991, Delia leads an itinerant and solitary life in London working as an agency nurse. When she meets fellow free-spirit John Sweeney in a local pub, it seems like the connection she has 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 he killed his former girlfriend and disposed of her body in an Amsterdam canal.
‘Sweeney is arrested but, due to a catastrophic failure by the court to realise how dangerous he is, granted bail.

‘He immediately pursues Delia and subjects her to a horrific, near-fatal attack. She survives, but Sweeney evades capture and disappears.’
Sweeney returns seven years later, and is arrested for the murder of another girlfriend – 31-year-old Paula Fields – in north London.
This leads to Delia having to face her tormentor in open court, as her testimony was ‘vital to the prosecution case against him’.
Discussing the role, actor Shaun Evans – who plays Sweeney – told Radio Times: ‘The story that we are telling takes place over about 15 to 20 years, over the course of a woman’s life – called Delia Balmer.
‘It is essentially about how this woman fell victim in one of her personal relationships to coercive behaviour, gaslighting, domestic abuse and violence.
‘She was ultimately let down by the judicial system until they really needed her as a linchpin in their case against the guy. That’s basically the gist of the story.’
Until I Kill You is available to stream on ITVX now.
