Grey's Anatomy Season 10 Premiere: Synopses, Photos Unveiled, Derek And Meredith To Leave Hospital

The "Grey's Anatomy" season 10 premiere is just around the corner, and we finally have the official synopsis for the two-hour episode.

"In the first hour, 'Seal Our Fate' (9:00-10:00 p.m.), the Grey Sloan Memorial Hospital doctors are faced with the devastation left by the storm. A giant mudslide in Seattle injures a group of first responders and citizens, causing the already shorthanded ER to spring into action. Meanwhile, Meredith is faced with a tough decision that will affect the life of a loved one, Callie is rocked by the reality of Arizona's infidelity, and Richard's life is in extreme danger," says the "Grey's Anatomy" season premiere synopsis, according to TV Guide.

"In the second hour, 'I Want You With Me' (10:00-11:00 p.m.), the fight continues to save those affected by the storm, Callie makes a bold decision regarding her relationship, and the doctors come together upon receiving devastating news."

In addition, a string of photos have been released for the "Grey's Anatomy" season 10 premiere, and it looks to be an emotional, dramatic return for the doctors at Grey Sloan Memorial Hospital.

So it might not be such a surprise that, after giving birth, Meredith and Derek will be taking a leave of absence to deal with their children.

"They're struggling a bit because they want to get back in the ER," says Patrick Dempsey regarding "Grey's Anatomy" season 10.

"They're just losing their minds and they want to have something else to do. They get stuck just doing dishes and diapers."
