The two-hour season premiere of Grey's Anatomy is almost upon us.

With less than three weeks to go until September 22, ABC has released the official descriptions for both "Free Falling" and "She's Gone," the two episodes that will comprise the opener.

Below, we run down each installment and post a trio of images from each hour. (Note: Plenty more photos to come this week!)

Free Falling: 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.

She's Gone: News of Meredith and Derek's unsteady relationship raises a red flag for Zola's adoption counselor; Alex quickly realizes that he has become the outcast of the group after ratting out Meredith; and Cristina makes a tough decision regarding her unexpected pregnancy. Also, Chief Webber brings Henry in for a last minute surgery, alarming Teddy.
