Malpractice plot

The thriller, penned by real-life former doctor Grace Ofori-Attah and from the makers of Line of Duty, is set in the Accident and Emergency department of a busy Yorkshire hospital. When Edith Owusu is brought in following a suspected opioid overdose, Dr Lucinda Edwards, who is heading up the team, leaves her in the care of a junior colleague while she deals with another incident. 

But when Edith dies, Lucinda’s actions become the subject of an inquiry by the Medical Investigation Unit. And, as Lucinda’s life spirals out of control, some shocking secrets emerge…

Malpractice — who is in the cast?

Alongside Niamh Algar as Lucinda, Helen Behan (The Virtues, Holding) plays formidable Dr Norma Callahan, who is heading up the investigation into Lucinda’s treatment of Edith and is determined to get to the truth.

Malpractice — interview with Niamh Algar

What is your take on Lucinda?

“She is hitting burnout and doing her best but she’s not in a good place. She was asked to choose which patient was more important. But there’s the trauma of thinking, ‘Did you do enough?’” 

How does she feel about being investigated?

“She resents being investigated because this isn't solely her fault. A combination of things went wrong, but she's been accused. She feels alone and that's terrifying. In every scene, Lucinda’s in peril. And she’s constantly making the wrong choice. But there’s something afoot that’s bigger than she knows…”

Is there an impact on Lucinda’s family?

“Lucinda and her husband Tom have a child and Tom is her rock, home is her anchor of safety and that’s what she’s trying to protect. But that becomes compromised…”

And how do you see her relationship with her superior, Dr Leo Harris?

“Leo is her mentor. Lucinda’s ambitious and wants to be at the top of her field as quickly as possible, so Leo is someone she respects hugely and, when his support for her lessens, she feels abandoned. James is great, it was amazing to have him on board.”

To prepare for the role, you shadowed staff at a real A&E department at a London hospital, how did you find that?

“It was amazing to get a glimpse of what it entails. The stakes are so high, but these people look after one another within a stressful, stretched sector. A&E is one of the hardest jobs because you're seeing someone on the worst day of their life, and it's relentless. They have an incredible quality.”

And what did you learn from Grace, the show’s writer?

“Grace was on set pretty much all the time and that was valuable, because she's talking about it from personal experience and I could check in with her. She’s very open about her time as an A&E doctor. It's amazing that she's taken a story like this but also mixed in the thriller aspect and family drama. It's unlike anything I've worked on before. It's not a glossy medical drama, it's very real.”

Malpractice — is there a trailer?

Yes, the fast-paced teaser shows Lucinda and her team during a hectic shift as things start to go wrong. The action also sees Helen questioning Lucinda about her decision-making, while a panicked Lucinda’s nightmare gets increasingly worse…
