This often campy series centers on the office of Dr. Sean McNamara and Dr. Christian Troy, longtime friends who practice surgery (and live life) in two entirely different ways. Christian is the stereotypical self-destructive playboy. Sean is the family man facing a moral crossroads, as well as a failed marriage to Julia. Sounds grim, but a healthy dose of dark humor keeps things humming and contributes to the show's appeal with both viewers and critics. But be warned -- the depictions of surgery on this series are a tad graphic.
