Let the healing begin. Season six's shocking finale stunned America and left fans asking, "now what?" This season will try to answer that exact question: there will be new beginnings for favorite characters with unexpected twists and turns for everyone. No matter what happens, friendship remains the doctors' saving grace.
How do you come back from one of the most gripping, harrowing, unsettling Grey’s Anatomy season finales ever? Well, you call in a psychiatrist. In the season premiere, the hospital staff is trying to deal with physical and emotional trauma in the wake of the deadly rampage of a vengeful gunman. As Dr. Perkins (James Tupper), a trauma counselor, is brought in to help in the recovery and to assess each doctor's readiness to return to work, Derek makes a spontaneous decision to resign as Chief and rushes back into surgery, taking everything a little too fast, and Cristina buries herself in her wedding planning.
After weeks of concealing the fact she was pregnant and miscarried, Meredith at last tells Derek and is finally cleared to return to her surgical duties in the wake of the hospital shooting spree; Cristina experiences post-traumatic stress disorder in the midst of an operation; and Bailey refuses to let Alex operate until he agrees to have the bullet in his chest removed.
Is that Dr. Shepherd we see walking down the hospital halls? It certainly is. But this Dr. Shepherd happens to be Dr. Amelia Shepherd. This shouldn’t come as a huge surprise. Addison has been pushing Amelia to leave the land of Private Practice to go see her big brother, who’s been ignoring her calls forever. She even brought him a present: a guy with a brain tumor. Think there’s a gift receipt?
Things are hostile on all fronts when a visit to the obstetrician results in some disturbing news for Meredith and Derek, and Lexie loses it when she notices Meredith and April getting closer. Meanwhile a car crash brings in multiple traumas and Jackson tries using his physical attributes to get ahead in the operating room, while Cristina's self-doubt carries outside of the hospital and into her house hunting with Owen.
As part of their training, Seattle Grace's residents are put in charge; the attending surgeons compete for a million-dollar grant.
A documentary film crew visits the hospital six months after the shooting to document the road to recovery for doctors and patients. The camera lenses follow Derek, Owen, Mark & Callie as they ambitiously perform a rare arm transplant surgery, Meredith helps Cristina put on a brave face for the cameras, and Bailey's patient, Mary, returns for her surgery -- which marks the first time they've all seen of each other since that fateful day.
The residents are pushed to their limits when Owen puts them through a rigorous trauma certification drill; meanwhile, Cristina is also tested when left alone to monitor a very ill lung transplant patient.
Top security measures go into place as a team of doctors, led by the Chief, try to save the life of a major policitcal figure from the Middle East. Meanwhile Cristina decides to finally decorate her new place and throw a housewarming party, and Alex shows up late from a weekend getaway to his first day of rounds with the new Pediatrics Attending, Dr. Phil Stark (guest star Peter MacNicol).
Derek lands the grant he needs for his clinical trial and all the attendings take him out to Joe's Bar to celebrate, but they get a surprise when they see someone they know already at the bar. Meanwhile, Meredith and Alex have to fend for themselves during the night shift with a nine-year-old patient who's experiencing post-surgical complications and his very pushy mother.
Despite Meredith's objections to the idea, a concerned Derek takes Cristina on a fishing trip in order to get away from it all, while Teddy, feeling directionless without Cristina, directs all of her efforts and compassion towards a dying patient (played by Scott Foley) who lacks the proper insurance to seek medical treatment.
