Synopsis by Hal Erickson
In the conclusion of a three-part story arc, the Seattle Grace staffers race against time to save Meredith (Ellen Pompeo), who after nearly drowning at the site of the ferryboat tragedy has been rushed to the hospital showing no signs of life. As she hovers between this world and the next, Meredith undergoes a spectacular near-death experience, "starring" several of her late friends and acquaintances--ranging from bomb-squad detective Dylan Young (Kyle Chandler) to her dear departed dog Doc! Meanwhile, the bond between Alex (Justin Chambers) and the seriously injured "Jane Doe" (Elizabeth Reaser) grows stronger; Izzie (Katherine Heigl) has serious issues with both Callie (Sara Ramirez) and George (T.R. Knight); Cristina (Sandra Oh) has yet another meltdown; and a major recurring character bids a sort-of-fond farewell.
