Week 1: Season Premiere

No job is more stressful, dangerous or exhilarating than those of the Firefighters, Rescue Squad and Paramedics of Chicago Firehouse 51. These are the courageous men and women who forge headfirst into danger when everyone else is running the other way and whose actions make the difference between life and death. These are their stories.

The doctors of Grey Sloan Memorial Hospital deal with life-or-death consequences on a daily basis -- it's in one another that they find comfort, friendship and, at times, more than friendship. Together they're discovering that neither medicine nor relationships can be defined in black and white. Real life only comes in shades of grey.

Set thousands of years before the events of The Lord of the Rings, this epic drama follows an ensemble cast of characters, both familiar and new, as they confront the long-feared re-emergence of evil to Middle-earth.

9-1-1 is a fast-paced exploration into the lives and careers of first responders – cops, paramedics, firefighters – the people who put their lives on the line to save others.

Mark Scout leads a team at Lumon Industries, whose employees have undergone a severance procedure, which surgically divides their memories between their work and personal lives. This daring experiment in "work-life balance" is called into question as Mark finds himself at the center of an unraveling mystery that will force him to confront the true nature of his work… and of himself.
