In Edinburgh in 1831, Dr. Wolfe MacFarlane runs a medical school where Donald Fettes is a student. Fettes is interested in helping a young girl who has lost the use of her legs. He is certain that MacFarlane's surgical skills could be put to great use but he is reluctant to do so. The good Dr. MacFarlane has a secret that soon becomes all too obvious to young Fettes, who has only recently been promoted as his assistant: he has been paying a local cabbie, John Gray, to supply him with dead bodies for anatomical research.
