Dr Lucien Blake left Ballarat as a young man. But now he finds himself returning, to take over not only his dead father's medical practice, but also his on-call role as the town's police surgeon. In season 3, Doctor Blake is pushed to his limits to find the truth behind a range of intriguing murders in 1950s rural Australia. They include the inexplicable death of a young champion rower; the murder of one of the town's elite who is found with a mysterious object in his stomach; the apparent trampling death by cattle of a well-loved farmer; and the murder of a respected surgeon whose bloodless body is discovered on the operating table.
