Trainee psychiatrist Doctor Hannah Wright is back where she worked as an intern: the general hospital. This time, instead of dealing with patients' broken bodies, she's tackling their mental health issues, with a roving commission to cover the medical, surgical and obstetric wards. All the while learning that mental and physical health are inextricably linked. Christina is planning to sue her obstetrician - Hannah's ex-boyfriend - for mental distress during labour. Junjie's Olympic dream has been shattered by injury. Is he at risk of taking his own life? Max's bipolar medication might keep him level-headed, but it is destroying his kidneys. And Ishani claims that setting herself on fire was an accident, but her story doesn't stack up. When she's not on call, Hannah finds herself navigating an unexpected friendship and the promising early days of a new relationship with fellow trainee Alex, before her grandmother reveals an explosive family secret.
