All Souls S01 E01 Pilot

"Evil has taken residence."

It is Dr. Grace's first day, having turned down both Yale and the Mayo Clinic to work at the hospital where his father was a janitor. He fails to save the life of Caroline Patterson, a patient who was moved to a basement room by a suspicious orderly. Dr. Ryman Kreeger, a senior doctor who thinks the "Gemini Project" will let him live forever, is taken by the hospital's ghosts.
