Meredith Grey and four other first-year surgical interns try to balance life and work at Seattle Grace Hospital.

The hospital is hit with an unprecedented crisis; Meredith and Cristina's surgical skills are put to the test.

Bailey treats a young mother battling breast cancer; Derek learns more about Mark and Addison's relationship; the interns defend a resident's competence at a staff meeting.

Alex gains the trust of Annie, a nervous patient with an extraordinarily large tumor, only to humiliate himself in front of her later. Meanwhile Derek chooses Meredith to assist with an elderly Parkinson's patient who may need surgery -- but Bailey disapproves of their relationship and is determined to make Meredith suffer -- and tensions escalate between Burke and Shepherd.

A patient's desire to end her life triggers haunting memories for Hunt; Arizona and Callie have different opinions about the future; Richard tries to adjust to his new role.

The doctors treat dozens of people when the roof of a romantic restaurant collapses on Valentine's Day; Meredith struggles with her new duties as the chief's wife.
