Trainee psychiatrist Doctor Hannah Wright has been thrown into the deep end of the outpatient clinic at Menzies Hospital. Her patients' health issues range from OCD to ice addiction, childhood abuse to the mental impact of ageing, and from bad parenting to bad genes. While Hannah comes under pressure to seek therapy herself to confront a traumatic past, her fellow first-years face problems of their own: on-and-off flame Alex is being bullied, Ndidi's marriage is in trouble, Jon feels isolated and Carey is concerned their autism will be a career barrier.
