Robert Young brings his Marcus Welby alter ego to television for one last time. Having retired, the good doctor takes a trip to Europe alone and falls in love with an American divorcee who is caring for a blind dancer.
Unfortunately the movie Marcus Welby, M.D.: A Holiday Affair is not yet available on HBO Max.
