Doctor Doctor (also known outside of Australasia as The Heart Guy) is an Australian television drama created by Tony McNamara, Ian Collie and Alan Harris, which premiered on the Nine Network on 14 September 2016, lasting five seasons, concluding on 23 June 2021. The cast includes Rodger Corser, Nicole da Silva, Ryan Johnson, Tina Bursill, Hayley McElhinney and Steve Bisley, and follows the story of Hugh Knight, a rising heart surgeon who is gifted, charming and infallible. He is a hedonist who, due to his sheer talent, believes he can live outside the rules. His "work hard, play harder" philosophy eventually comes to 'bite' him. The series was originally produced by Essential Media & Entertainment and Easy Tiger Productions in association with Screen NSW. Andy Ryan and Jo Rooney served as executive producers.

Plot

After a spectacular fall from grace, high-flying heart surgeon Dr Hugh Knight receives a life-changing punishment from the Medical Tribunal—he is forced to work for a year as a country general practitioner (GP) in his former home town of Whyhope. Now the only way to salvage his brilliant career is to work as a lowly GP in an under-resourced, small-town hospital surrounded by estranged family, former friends, crazed colleagues, oddball patients, jealous brothers and a newlywed ex-girlfriend.
