Trauma focuses on two fathers Jon Allerton (Adrian Lester) and Dan Bowker (John Simm), whose lives collide when Bowker's teenage son is fatally stabbed, dying in Allerton's trauma unit. 

Bowker blames trauma surgeon Allerton for his son's tragic death and embarks on a desperate hunt for justice he struggles to deal with his loss, with Allerton as his target. 

As Bowker unravels every aspect of Allerton's life, it poses the question: is his grief overpowering his judgment or is there more to Allerton than meets the eye?

Rowena King (Of Kings and Profits) stars as psychiatrist Lisa Allerton, wife of Jon and mother of their teenage daughter Alana, played by Jade Anouka (Chewing Gum). Lyndsey Marshal (Trespass Against Us) plays Susie Bowker, Dan’s hard-working wife and mother to their children Alex, Catherine and Mark.

"We are delighted to have such a fantastic cast, led by John and Adrian, to bring this gripping modern British story to the screen for ITV," said producer Catherine Oldfield, who developed the show with Mike Bartlett.

Writer Mike Bartlett commented, “I wrote Trauma knowing we needed, and hoping we'd get, hugely talented actors for the roles. But this cast has exceeded expectations. I'm a huge fan of all of them individually and can't wait to see them on screen together.”

ITV’s Head of Drama, Polly Hill said, "Mike Bartlett's brilliant new contemporary drama, Trauma, is a moving and powerful story about a father who loses his son, and the surgeon who tried to save him. 

Trauma begins filming this summer in and around London.

Adrian Lester will also star in upcoming Sky Atlantic drama Riviera, and has directed two episodes of the drama. Meanwhile John Simm will be returning to Doctor Who as the notorious villain The Master for Peter Capaldi's final series, after a seven year absence from the sci-fi series.
