Dr. Sean McNamara (series star Dylan Walsh) and Dr. Christian Troy (series star Julian McMahon) are plastic surgeons, best friends and business partners who run McNamara/Troy, a prominent South Beach practice. A seemingly conservative family man, Sean has come to realize that his financial success and perfect home can no longer mask the problems of his marriage. On the other hand, single and often promiscuous Christian has few inhibitions and enjoys the benefits of his lucrative career and good looks, even as he yearns to have a family of his own. Sean's marriage to disillusioned Julia (series star Joely Richardson) is crumbling, and his relationship with his 18-year-old son, Matt (series star John Hensley--not appearing in this episode), is troubled and tense. Dr. Liz Cruz (series star Roma Maffia) is the team's opinionated anesthesiologist.
