REPACKAGED. It's always rush hour at the ER. Each day - each moment brings new challenges, triumphs and losses. No one ever expected those losses would include one of County General's talented med students. the pell-mell ER rotation continues with the 22-episode Season Six of the award-winning series (presented with DVD extras). New stories unfold as young doctors (portrayed by Goran Visnjic, Michael Michele, Ming-Na and more) face the day-in, day-out rigors of life-and-death decisions as a veteran physician (guest star Alan Alda) faces a bittersweet conclusion to his career. Old stories resolve: Boulet finds love and family; Hathaway gives birth to twins and makes a decision fans have long awaited. And tragedy strikes - swiftly, irrevocably and for survivor Dr. John Carter, perhaps irreparably.
