Too Close follows Dr Emma Robinson (Emily Watson), a forensic psychiatrist who is assigned to assess Connie, a patient accused of a terrible crime that she cannot remember committing.

Robinson attempts to determine if Connie is fit to stand trial and learns of a complicated relationship between Connie and her beautiful best friend Ness, who appears to have a strong influence on her mental condition.

As Robinson begins to uncover the truth, the psychiatrist is quickly thrown into a twisted psychological game. Connie starts to exploit Robinson’s deepest insecurities and what was initially a pursuit for justice soon turns into a battle of the minds.

“Too Close is a brilliant script where you are never sure who has the power - the psychologist or her patient,” said commissioner Polly Hill, Head of ITV Drama.

“I’m delighted that Emily Watson is going to play Emma, who will be phenomenal and I’m looking forward to working with Ruth Kenley-Letts and the team at Snowed-In Productions to bring this fantastic adaptation to ITV.”
