Recipient of the 2007 Golden Globe Award for Best Drama Television Series and multiple Emmy nominations, including Outstanding Drama Series for the past two years, "Grey's Anatomy" returns to the ABC Television Network for its fifth season. Is "happily ever after" possible for Meredith Grey and Derek "McDreamy" Shepherd? With Meredith experiencing a breakthrough in therapy - the realization that she and Derek can be extraordinary together, rather than ordinary apart -- she and Derek now face the highs and lows of being a committed couple. Continuing their first year as residents at Seattle Grace Hospital, Meredith, Cristina Yang, Izzie Stevens and Alex Karev have interns of their own to mentor, including Meredith's half-sister, Lexie Grey. Lexie has become a roommate and confidante to George O'Malley, who, after divorce with Callie, a breakup with Izzie, and learning that he failed his residency test by only one point, is striving to get both his professional and personal life back on track. After attending to his girlfriend Rebecca's mental illness on his own, and revealing that he had gone through this with his own mother, Alex finds solace in Izzie's arms. Alex must continue through this difficult time, whether or not Izzie remains by his side. Cristina, having finally won out over her tough-as-nails mentor, Erica, is back on track as a surgeon - but is there a chance for new love in her life as well? With the encouragement of Mark "McSteamy" Sloan, Dr. Callie Torres has taken a chance on love with cardiothoracic surgeon, Erica Hahn; now, she and Erica must figure out what happens after the first kiss. Overseeing the residents is the no-nonsense Chief Resident, Miranda Bailey. Facing marital troubles and the difficulty of balancing her work and personal life, Bailey has handed her responsibilities as head of the free clinic over to Izzie. Also striving for balance is Chief of Surgery, Richard Webber, who has reunited with his estranged wife, Adele. The doctors of Seattle Grace Hospital deal with life-or-death consequences on a daily basis - it's in one another that they find comfort, friendship and love. Together they're discovering that neither medicine nor relationships can be defined in black and white. Real life only comes in shades of grey. "Grey's Anatomy" stars Ellen Pompeo as Meredith Grey, Patrick Dempsey as Derek Shepherd, Sandra Oh as Cristina Yang, Katherine Heigl as Isobel "Izzie" Stevens, Justin Chambers as Alex Karev, T.R. Knight as George O'Malley, Chandra Wilson as Miranda Bailey, James Pickens, Jr. as Richard Webber, Sara Ramirez as Callie Torres, Eric Dane as Mark Sloan, Chyler Leigh as Lexie Grey, and Brooke Smith as Erica Hahn.
北京时间9月25日，ABC电视台重磅医务剧将以两小时特别篇回到我们的视线，上一季结尾留下的Izzie和George的去留问题将在回归篇中一一解答。感谢KatherineHeigl的直言，我们已经大概得知剧中这两位主要人物的命运。Izzie将会幸存下来，而George将告别观众。而且因为TRKnight的合同问题，George可能将不会再以新镜头出现在第六季中，开篇也仅仅将以一具棺材代替他的存在。ABC电视台也确认George的扮演者TR Knight将不会成为第六季的常规演员，与之相反的是扮演儿科医生的Arizona Robbins的JessicaCapshaw将有幸成为第六季的常规演员。可以预见，其与剧中另一主要角色Callie的同性恋情的戏份也将加长。
The fifth-year residents return for the first day of a year that will make or break their careers: Meredith faces the consequences of tampering with Derek's clinical trial and is terminated at the hospital; April tries to step up to the plate as Chief Resident in the wake of a giant sinkhole in the middle of Seattle; and Cristina and Owen are still at odds over their drastically different feelings for their unborn child.
