Marcus Welby, M.D.

Dr. Steven Kiley befriends a former employee, now a reformed drug addict, and in doing so places himself and Dr. Welby in an awkward and almost untenable position. Dr. Kiley does his best to help Warren Chamber -- his onetime benefactor -- find suitable employment, but his record as a former addict precludes any success. Finally, when a job as a bus driver with a private school becomes available, and Kiley is called on to give his friend a physical examination for the institution, he is forced to choose between his duty as a doctor and his obligation to a friend.
