Whishaw will play the on-screen version of Kay, who also adapted the memoir for TV, which will explore what it means to be a good doctor in a system that is buckling under pressure from all angles.
Kay created the memoir using his diaries which were written in secret after sleepless nights and hectic days, giving the honest truth of what it means to be a doctor working in obstetrics and gynaecology.
The series sees Whishaw playing Kay, a doctor suffering from 97-hour work weeks, while making life and death decisions and dealing with surmounting pressure and responsibility.
